easiest mod you can do yourself

That's the thing. The only other guy I know that has a 370 has k&ns on it. Idk anyone else where I live that has a 370 that can help.

Very helpfull information here :tup:

I would lean towards doing it yourself, But if you have NO tools and NO mechanical skills?

Then yea find a local member to help so you can do it or have a shop install them for you.

AK's Diy is pretty detail so you shouldn't have a problem.

The only thing I can't stress enough is to be very carefull in removing and installing the maf sensors.

Only issue that might cause problem is scratching the bumper and fail Protect your AC lines from damage.

Bro if you can jack your car up and remove the tire (change a flat) you can do the intake install. If you want Stillen but want K&N because of the easy install then just get the Stillen Gen 2 intakes lol :tup: It’s the same as the K&Ns with different color pipes and the name.

If you're not comfortable with working on it yourself, have someone qualified to do it. It seems like you've never done this sort of thing before. It's really not that hard to install the gen 3's, but you can mess up something if you're not carefull. Something as simple as installing the maf sensor to the new tubes for example. I don't want to scare you, but you could end up paying a lot more than $175 if you mess up. Only you can decide if it's within your abilities. The bumper removal is probably the easiest part of the install.

I would like to do it myself but like you guys have mentioned it might be too much. AK wrapped 3M around the AC wires if I remember correctly. Anyone else do this??

The small hose that comes with the G3's is longer than needed for the connections to the manifold breathers. Just take the extra, slit it down the length and zip tie it on the ac lines.

Sweet. Thanks man. Hey those of you who have the G3s. Did you notice a huge drop in mpg or not really? I feel like a bitch asking about conserving gas but I was just wondering. Thanks

I don't have the Stillen CAI, I have the Takeda one, which is similar, and I didn't notice any drop. I can almost average 30 mpg on the highway still.

Installing my CAI was my first mod ever, and I had to go out to buy a wrench set because I had nothing but an adjustable wrench which was unable to get the bolts at the bracing. Of all the engine mods to do, this'd be the easiest. You could always ask a friend for help and tools. Then again, if you actually feel uneasy working on your car, then definitely take it too a shop. You'd be kicking yourself pretty hard if you end up scratching your bumper or braking a MAF sensor just to save a hundred buks or so.

I've noticed that people usually lift their cars when removing the bumper. Do I HAVE to life the car if I want to remove the bumper?

To take the front fascia off you have to take off the engine undershroud plastic piece. I know at least on a Nismo to take off the undershroud you have to get the front end in the air.

You don't have to lift the car. You can get a ratchet under there.

well im going to order intakes next week. I just want to make sure im gonna make the right decision. im tempted to do the install myself but idk, don't wanna mess up the car and pay for it later. :wtf2:

One last question guys. Are the chances of hydro locking higher with the stillens? I know injen and aem are more likely to hydro lock but is it the same for the stillen? Thanks

You'd have to put the entire front end of the car under water.

Like drive down a boat ramp until the water is up over the hood.

Which would also make the stock boxes hydro-lock. (though it would probably kill the engine before it sucked enough water in to matter)

There is no way in hell you can hydro lock the Stillen G3 intakes. Take a look here for filter location STILLEN 370Z Generation 3 Ultra Long Intake Released! : STILLEN

For the gen 3s you have to shave part of the front core support. It's not just 100% bolt in. You will have to trim the support with a dremel tool around the hole where the intake tube goes to the front of the radiatior. If you are not technically inclined to do this i would just pay the fair price of 175$ and have someone with more experience do it. You have to remove the bumper and old intakes etc etc, things could easily get complicated if you're not a DIYer.

Super easy to install the Stillen intakes. It was the first mod I installed. I have never worked on cars before so I brought a 6 pack of beer over to my friends house and he helped me. Took us an hour to get it installed. Follow the DIY here on the forums and it is really really easy.

Thanks guys! I'm ordering my g3s tomorrow and gonna install them at a shop after my finals finish. I would prefer to do it at a shop cuz if for whatever reason they mess up i can take my car back and fix the problem with them. Then in 2 months I'm gonna install the berk exhaust!!

Air Intake /new/ options ??? Help???
 

I have a 2010 370 Z NISMO and have the factory filters in it now. I tried K&N filters in my other vehicle and it screwed up the electronic O2 cesors and other things which ended up costin me a small fortune to fix.

What I would like to know is if there are any AWESOME air intakes that can be installed that wont hurt any censors. I realize it will void the factory warantee however I never will sell my car so I am not worried about isseus with the warantee.

Can anyone recomend a cold air intake system that is going to boost HP a little and or be O2 censor/electronic friendly?


Thanks for reading.....

I installed my Stillen CAI the day I got my car. No issues. But I was told it runs very Lean that way and you should get a tune. I didnt tune it until I got my whole system installed. CAI, Test Pipes and Cat Back, then Tune. Gained about 30HP.

Stillen Gen3 is probably the most common CAI out there for the Z.

I'm very confused as to what happened with the K&N filters on your other car. They are a solid budget choice for the Z (I ran them for a few thousand miles before getting the R2C intakes), and I don't recall seeing anyone have problems with them.

Also, it won't void the warranty. However, any part that fails will not be warrantied if the dealer can claim the failure was a result of the installation of any aftermarket parts.

Stillen G3's are the way to go. Just be warned that on a Nismo there's a couple small plates behind the fascia that have to be removed/trimmed.

Me too. The only thing I can think of would be over-oiled filters, but that wouldn't cause any issues that a $3.99 can of MAF sensor cleaner wouldn't fix.

ikr...

ive had the K&N's in for almost 2 years. i even washed/re-oiled them last year. how did yours ruin the last engine?

Have to agree with the majority here, and ask if you may have over oiled your K&N's? I've used them on nearly every car I've owned in the last 10 years, as well as my last two motorcycles. Properly cleaned and oiled, they work awesome. With the cost of two for our cars at > $100, and the Stillen G3 costing 5x's that much, I'm sticking with the K&N's for now. Our intakes draw in cooler air from the front of the radiator area anyway, so I really don't see enough of a difference to match the cost.

Best cold air intake for 370z?
 

I've researched a lot and it seems like Injen is often the most favorable. What is the opinion of some of you? I'm a big fan of Stillen too and wondering about that as well. Please share thoughts before I make the purchase. Money is not an issue either.

No... Way... An intake thread...


The forum favorite is NOT the Injens, it's the Stillen G3



/thread

I browsed for an intake thread already open but didn't see it. Thanks for the reply!

Stillen

i think it is all a waste of money since its just a pipe with a filter on it

imo DIY intakes would be the best so Modshack's intakes or Post MAF tubes and k&N Drop-ins

The one you make for cheap and don't blow $500+ on.

Just to be honest some people want the stuff under their hood to look nice. I mean this isn't a $3k Honda here... Just my .02

Yeah, I don't plan to jimmy-rig some makeshift intake. I do want everything inside and out to look clean and be legit. So I'm thinking Stillen G3 CAI it is.

It's all a matter of priorities. Some people will spend $2k on a Ti cai. Most people buy a Stillen g3. Some people will DIY. I've got $10 that says everybody ends up within 5 whp of each other.

:iagree: even WITH the variable of different dynos, lol

I would rather pick up AAM's... Not mentioned here but has a very similar design as G3's and has a novel sleeve that will size down the maf for untuned guys and you remove it when you get your car tuned.

Then again... this thread is very redundant

There's no " best" anything when it comes to NA mods. Once you do all the usual bolt ons and tune, you'll be around 320-330 whp after a tune no matter what brand you buy.
