K & N short intake...opinions
 

I bought my car a couple months ago and already have the bug "stronger, faster, louder". Problem is I pretty much haven't filled my pockets up yet after the big purchase. In my country the car costs 80k. I thought about the K&N short intake as seen in the picture. I know there is almost no recognizable hp gain. I am interested in having the engine sound louder; more of a roar. I don't want the longer pipes because I can't pass inspection with any intake kit what so ever and I don't feel like taking off my bumper every time a cop stops me and sends me to inspect my car.
Questions :
1. Does the K & N make the engine considerably louder at wot?
2. Does it in any way cause harm to the engine?
3. Does it mess with the ecu?
4. Would an ecu upgrade from uprev be worth it at this juncture when all i'll have is the intake system.

Thanks

I'm still fairly new here in the forum, but from what I've read here, the Typhoon will change the sound of your car, I haven't seen anything about harm to the engine. The only engine related issue that I've seen is that because the Typhoon is a short ram system, and is on top of the engine you may be sucking up hot air instead of fresh or cold. I haven't see anything about the ECU and no need for an uprev with just and intake, your ECU will adjust to that simple part. I was going to get this system but went with the Gen 3 instead. Enjoy the car and shopping for mods.

any short ram intake should do OK in cooler climates

if your in a warmer climate you may suffer from heat soaking due to a lack of heat-shield presence.

Are you guys for real? First off if your worried about it sucking up hot air, don't because the stock intake does the same and its oem. Secondly, the short ram comes with a heatshield as shown in the picture.. Smh.

They sound great! Don't worry about ECU upgrade until you at least do HFC and CBE exchange too.

Stock intake airbox sucks up air from behind the bumper. It is not the same as an open short ram as shown in the picture. Also, if installed as shown in the picture, there is no heatshield, and hence, someone who isn't familiar with the product would not know any better.

Well it seems buddy boy your not familiar with the product. In the pic above there is a heatshield present. The system does come with a heatshield that does seem to block out a fair amount of heat. I have the system and the sound is awesome. I noticed no lack of power what so ever. All in all I am very happy in every aspect of the induction! I got mine on amazon for 296 shipped but that was about a year ago.

:iagree:

I have the Typhoon intake and it does in fact have a heat shield, in the photo you can see the black rubber bumper between block and the intake that snugs up to the hood when closed. The one on the other side is lower and you cannot see it in the photo

Granted, it ain't a great one, but it has one.

I am happy with mine, it does make some noise at wide open throttle. It has caused no ECU issues for me. If I had to do it again, I would still buy it.

So that leaves us with the stillen generation two which has the heat shield above the filter as opposed to below like the k & n. Which is better against heat soak? I would think that a heat shield below would be better because the engine hood must prevent some heat soak. I live in a pretty hot climate 8 months of the year. (90f)

[QUOTE=Shamrock;1763976]In my country the car costs 80k????:wtf:
Am I the only one that noticed this?

Yes that is how much it costs. Taxes, taxes, and then taxes. The k&n or stillen will cost me close to a grand.

i would do some online searching to find them cheapest possible

I am only interested in short intake. No bumper hassle.

Go with Post MAF tubes with K&N drop ins and call it a day. Z1, HPS, Mishimoto etc can hook you up.

:iagree:

if only interested in short rams then don't bother. do what speedfreek said.

i did the same with mine because like you i didnt want the hassle of removing re-installing the bumper, though not a hard task to accomplish, i just didnt want to do it.

2 x K&N drop ins
33-2399 - K&N Replacement Filters, Replacement Air Filter direct from K&N

and these HPS replacement hoses:

cheaper than shortrams and no risk of heatsoak

or get them both from one place...

Z1 Silicone Post-MAF Intake Hoses

So if one was to get the K&N Replacement Filters ($122 for 2 filters) & the HPS Silicone Post-MAF Intake Hoses ($110) you are only looking at $232. A guy stated that he did a dyno 3x's with the K&N Replacement Filters & he received 10whp. HPS Silicone Post-MAF Intake Hoses is stating 6.77whp. I'm guessing that if one opted to go with the Z1 Silicone Post-MAF Intake Hoses instead of the HPS Silicone Post-MAF Intake Hoses that the whp would possibly be the same. Ok at the end of the day one could possibly assume that if he/she went with both K&N Replacement Filters & HPS Silicone Post-MAF Intake Hoses (or Z1 Silicone Post-MAF Intake Hoses) that you can possibly have 11-14whp (maybe 14-16.77whp with tune)?

sounds about right....i would guesstimate 12-13...

Sorry I don't understand. K&N drop-ins with post maf hoses will give the same horsepower upgrade as the K&N short ram intake.

1. Will the engine sound as loud with the drop-ins?

2. Why no danger of heat soak with the drop ins?

3. How can the drop in filters plus maf set up be the same hp as the K&N short ram?

Please explain. I am no mechanic.

You will get about the same sound as stock. You will not be displeased with the K&N Typhoons. They look and sound better than any other out there IMO! I drive in the Texas heat and have not felt that the heat has any effect on performance at all.

This subject has gone round and round. Everyone has an opinion on it. My take is this. If you do not want to go with a long tube setup to get true cold air with the Stillen G3's or Takeda Stage 2 setups then I would go Post MAF tubes with K&N drop ins. The short ram kits are nice and look good under the hood but the effects are minimal over the Post MAF setup. Plus on top of that most already have a CBE of some sort and the returns from the intake systems will be even less. It comes down to how much you are willing to pay for a few more hp and looks. Mainly I think its the latter if you like the look of the system and want it than get it...if it gives you a few more hp and at the very least doesnt take away any then its a win/win.

1. Will the engine sound as loud with the drop-ins?

No it will not sound much louder if any. Everyone's ears are different but it will have minimal effect on sound.

2. Why no danger of heat soak with the drop ins?

People will argue that Short ram kits such as the Typhoon will suffer from heat soak due to the style of heat shields used. There are reviews saying they are great and some saying they are not worth the extra money and suffer from heat soak. The filters are no longer fully enclosed in a air box and when the temp gets hot under the hood some claim they are more susceptible to heat soak. I think the stock air boxes are probably just a susceptible as well, maybe slightly better since they are fully enclosed.

3. How can the drop in filters plus maf set up be the same hp as the K&N short ram?

They will not be the same. On a stock car the Typhoon kit will open the engine up more yielding you the 13-15hp they claim much like the Stillen G3's will yield you the 18hp they claim. If you already added or plan to add an exhaust system the gains are not stackable. So if you installed the Typhoon kit and netted the 13+ hp gain and then install an exhaust system that claims 20+ hp gain you will not get a total of 33+ hp gained. The rate of return diminishes with each bolt on.

That is where it comes down to what looks nice, sounds good, and price come into play. If you like the way the Typhoon kit looks and are ok with the price then you will get some hp gains and a more aggressive sound.

If it is about price alone. You can get a Post MAF with drop ins for around $190 shipped and the Typhoon kit goes for around $300 shipped. Assuming most who mod thier cars will have a CBE of some kind. The Typhoon kit will give you a few more hp gains over the Post MAF setup with a more agressive sound. However is the $100+ price difference worth it? Well that is for you to decide.

1. About the same as stock, there may be a slight hiss on cold start.

2. They are made of silicone instead of metal which has much greater heat resistance.

3. The stock intake setup is already quite good, changing out the tubes and filters only improves upon what is essentially a CAI system by slightly increasing air flow and heat resistance. If you use short rams you are going to lose the CAI benefits of the stock setup.

The Stillen G3 claims 18.33whp, Takeda Stage 2 Intake claims 15whp, K&N Typhoon 13-15whp & the K&N Replacement Filters plus Post-MAF Intake Hose (10whp for filters & 6.77whp for Post-MAF) 16.77whp (doubt it would be this high).

Yes I do agree that if one already has a CBE (20+whp) & adds mods (CAI 15whp), then you will not get 35whp. If you want to get back some of the hp that you lost by adding mods to the car, then you should get a tune.

Have them on my car and I love them :tup:

Had the HPS MAF Tubes and K&N Filters on before and it was significantly slower than it is now. Don't believe everything you hear on the forums.

Really......... I have my mind set on the Takeda, but these K&N filters & Post-MAF caught my eye as well. I agree with what you are saying about not believing everything you read. I believe one will never go wrong with Stillen G3 or the Takeda Stage 2 Intake. So what did you switch too? How was it actually slower? Did you have CBE & if so did you get a tune?

This is why I'm going with the Typhoon kit.
Nice and concise opinion, thanks!

I meant to say that my car feels faster now with the K&N Typhoons than it did with the MAF Tube and Filter combo.

And yes I have test pipes and a catback, no tune. However mines a Nismo, it already comes with a factory tune (don't know how much difference that actually makes)

just get the typhoons and be done with it.. sound is bad azz and u open the hood it looks fantastic!

reported:shakes head:

Installed the K & N Typhoon today and I like it. Can't say there's much of a power increase but it definitely is more responsive at upper RPM's.

Unfortunately there seems to be a buzz like an elelctric razor from 4-5K so I'm not sure if that's a rattle or loose part. :shakes head: I checked everything and it's all good. Anyone else experienced this?
Might be coming from the drivers side......

did that guy report me for saying azz? Man he is very sensitive lol, I have not heard any rattling at all on mine, somthing has to be loose or vibrating
