This website I was looking at had two different K&N CAI's, a 63 series Air Charger CAI and a Fuel Injection Performance Kit. The 64 series is almost $80 cheaper than the FIPK...what is main differences between them?

Anyone have either one of them? Is the difference worth the price difference?

Any help would be great

 

Most likely the $63 on is just the filter and tube from filter to maf. Where as the fipk kit should include filter, tube from filter to maf, and tube from maf to throttle body

 

the more expensive one is the complete open filter kit, the cheapr one is prolly just the filter alone.

 

not sure which systems you are refering to... But the cheaper FIPK makes more horse power thatn the Typhoon Kit

 

In order from left to right: K&N 57-2519-3, 69-3521TP, 63-1008. Best, Better, Good...
