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.

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...

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.

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?

[olddudesrule]

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.

First of all, thank you everyone for replying and giving your input on a few previous threads. After long thought and research, I ordered the FI exhaust system. I did not order the RHFC yet but am 90% sure I will before my exhaust ships in 7 weeks.

Having said that, the only mods I will do for performance will be exhaust, rhfc, and maybe intake. After hearing feedback from last thread concerning the intake, I figured this was worth starting a new thread.

I have narrowed the I takes down to the following.

1. Injen sp1989. $490.00
2. Injen sp1990. $499.99 (what's difference?)
3. Stillen generation 2 $422.00
4. Stillen generation 3 $535.00

Questions:

1. How much estimate hp will these add?
2. Which ones require removing the front bumper? And is it the full actual bumper that has to come off?
3. Which ones are easiest to install and maintain (changing filters )
4. Do these filters last similar to regular air filters
5. If I do the intake as well as other mods, do I need a tune? I have heard no and yes. Some say you can lose hp if tune isn't necessary.

Thanks for all your help

Also, if there is a better intake system out there let me know. Not set in these, they just seems to be the best ones I saw online. Don't care if I spend a few more bucks to get a good one.

[Chuck33079]

either buy the Stillen G3 or get a set of silicone MAF hoses and K&N drop ins. Stillen for the most power, or drop ins so you don't have to pull the bumper to clean the filters. Do not buy any intake that pulls air from the engine compartment. If you're not willing to pull the bumper (a 15 minute job) then go with drop ins.

[370ZYZFR1]

How long will generation 3 filters last?

[Chuck33079]

Forever. They're K&Ns. Buy the cleaning kit and wash them every 10-15k like you would with the drop ins.

In theory, every 50k miles, but some $20 hydrophobic socks, 100k




Get the Stillen G3's or a similar equivalent

I vote for R2C intakes. They look great, easy installation. The filters are super easy to clean because they are dry and do not have to be oiled. and the biggest plus I saw was NO BUMPER REMOVAL.

If you can't get the filters out of the engine bay getting an intake is worthless. Pick up the silicone intake pipe and drop in filter combo from the Z1 link a few posts up and call it a day
