Can anyone give me the Part # for k&n air filter that fits the FX45

 

[PhilP69]

Just put one on last week...

P/N 33-2229.

Thanks

Perhaps a dumb question...

Doesn't that void your warranty?

 

[kcrudup]

No.

 

[krzys4]

Thanks

other dumb questions
what difference does a K& N filter make?
what does it cost?
is it easy to install?
like i said these are'nt the smartest questions although a lot tougher than the ones they ask at the presidential debates

Now that you mention it, can you answer these questions or do you want me to search.

supposedly add about 5 HP....i would say 1-2 at most by allowing better air flow

Better filtration than the stock paper filter.
Reusable
Cost about 15 bux...check Kragen or autozone
Super easy to install

Off a bit on your picing... try $45.

forgot to mention used price.. I've sseen them sell for 15 bux on g35 and 350z forums

I've noticed a difference, pulls harder in the mid range IMO.

 

[FromHereToInfiniti]

I just installed mine a few weeks ago. Any difference that I could tell could be attributed to the drop in temp outside too, so there's no telling. Your butt dyno won't notice a 5 or less HP increase anyway...though there's always that placebo effect.

I have them on everything I drive and give them to friends.Cost effective ,yes,Power-subtle feel,but you do feel...but 5 seems high 1-2 seems realistic.I have a new spare for $35 plus shipping.Iwent with a new design.Your call,not pushing!

I've always used a K&N or BMC filter on every car and bike I've owned. Well worth the realistic max gain of 1%-2% HP at higher speeds. I'd say about a realistic +3HP MAX rear wheels to the 315HP MAX @ ?? RPM for our normally-aspirated 4.5L V-8s though more or less depending on which RPM and road speed. Do a search for some K&N dyno runs and especially many articles of ricer racer runs to see differences between STOCK vs. K&N vs. CAI (They love to gauge the most minute performance changes). I've never had a problem with fouling MAF sensors, cleaning and re-oiling, or having to change one out due to negative effects.
