So I see that K&N makes a few different intakes for the VQ40. Does anyone now the difference between the FIPK and the 66 Series?
PS, I also just wanted to get a theard in this section.

I should have went to the K&N site first. Here is the answer I was looking for.Fofiddy wrote:Composite VS Aluminum, in theory the composite would resist heat from the engine bay where as the aluminum although more "effective" than stock will still pick up heat from the bay... you can also look at dyno charts on www.KNfilters.com.
the 77 only gives you 11hp (at 5200rpm) but it gives it to a 2-3hp benefit starting at 1800rpm
The 57 giver 14hp (at 5075rpm) but doesn't improve anything untill 3700 rpms but kicks in with a 10hp gain, funny thing on K&Ns site the 57 series dyno dropped the data before 3300rpms.
No info on a 63 series on K&N's site
the 57 is the FIPK btw
