370Z K&N Dual Air Filter

ZKindaGuy · 06-17-2009, 07:25 AM

Does the 370Z use the same K&N dual filter size as the 350Z or did the dual air-filter size change on the 370Z?

I think most will tell you the same thing: dont waste your money. The drop-in filters tend to do nothing but take performance away, and jack up your MAF thanks to the oils in the filters...

Ouch! Do you have anything to back that up? Not flaming, but I have always used K&N filters in my cars. I have always seen a bit better performance, fuel mileage and sound. Take a look at K&N's site, especially this page regarding MAF's.

As far as the original question... I don't know

As for the original question, why not just go to K&N's website and look it up? They've got a database that lists all the part numbers for each car.

I can tell you with absolute certainty that the 350 with dual air boxes and the 370 take the exact same filter size; if you have two K&N filters in your 350 you can drop them right into your 370 (I'm not sure about the earlier 350s with one air box; I've never had reason to check into it.

As to whether they reduce performance I think that's a bit of an untested/undocumented theory but for me at least, it sort of misses the point...I use K&N filters because I believe they provide better filtration without overly reducing airflow.

Obviously, however, a dirty filter, K&N or otherwise, is a BAD THING so whichever you use, keep them clean or keep them replaced on a regular basis!

...or get the Stillen G3 intakes for the best of both worlds

ZKindaGuy · 06-17-2009, 09:23 PM

Thanks..I figured the 370Z filter size would be identical to the 350Z. I just will have to go buy a pair as I never yanked them out of the 350Z I previously owned. As for the comment regarding K&N being bad or a waste, I have been using them for 40 years now in Mustangs, Z's, Pickups and SUV's and never experienced a problem but always pickup up positive throttle response in all the vehicular types as well as some dyno-proven RWHP even with the panel ones. So I don't subscribe to the "NO K&N" beliefs.

Ouch is right!

If you're having MAF issues when using K&N or any washable filter that uses oil, then you're improperly oiling the filter (END of that question).

Just when my tuner had to clean off my MAF thanks to my K&N (that was still fresh, btw - never cleaned or re-oiled it...) dropping its oil all over the wires, and jacking up the air readouts

. And a legion of LS1tech-ers who found the same problems.

But hey, its your money, spend it how you well - we just found Wix filters filtered just as well and were dirt cheap.

Im with the others on saying, just save the cash for a real intake kit, btw.

As my previous post said, then, I guess K&N cant do it from the factory

My basic thoughts.

With regards to aftermarket intake kits; unless you are doing some forced induction or something similar; the only thing an intake kit will do for you is look good and may give you some nice sound effects.

As far as engine performance goes; it's my understanding that the stock air box set setup provides all the airflow that the engine can handle.

Notwithstanding your forced induction reference, lots of folks don't understand the air flow dynamics involved and the importance of the point you are raising.

With a cold air intake kit, a person can put it on the car but likewise if they don't upgrade to a less restrictive exhaust as well at the same time then they are not going to see the benefit that can be had from adding the CAI as it works in conjunction with the entire exhaust.

For me, I just want the less restrictive intake airflow the dual K&N type panel filters bring to the table as with the 350Z I once owned it made a word of difference with the throttle response. From a HP perspective if I gain a few by dropping the panels in thats nice but I have reached the lifestage in my life that I no longer have a "more HP" addiction.

Come again, Robert? So the measured gains people have seen on the dyno from the Stillen G3 intakes are what? A complete fiction? Or am I not understanding you?

K&n filters do seem more heavily oiled new than what i go for when i re-oil them.
