Wide open throttle is definitly improved... epescially after the new exhaust.... it definitly improves the powerband..... fuel economy, ehh,maybe.... the sound is MUCH better.... worth the investment, definitly...

 

ok today I finally purchased the K&N FIPK Gen2, should be here in a couple of days

 

Hows it working for you...?

Any improvements to your day to day driving?
better throttle response?
better MPG?

or worse?

 

After having my truck,then a few more vehicles since, I am more a fan of directfit filters for day to day use. Low end goes away with the conical filters.The air hat on top of the throttlebody is there for a reason I foudn out, to boost lowend. YES, wide open throttle, the conical is better, otherwise, do a direct fit, keep the factory airbox unless yer a diesel.

 

I'll have to disagree here.
I noticed a definite improvement in part throttle acceleration with the K&N FIPK vs the stock setup with a clean K&N drop in filter. No perceivable loss of low end by me.

Most stock air cleaner systems are designed to be quiet as the primary concern. Performancefar down the list.

 

I saw little to no gain in performance and MPG with the cold air intake. I switched it for one of the round 14x3 air cleaners about a year ago in December and also saw little to no gain in performance and MPG.
