has anyone that has a aftermarket drop-in air filter noticed an difference in Hp/aceleration w/ the 5.9's

thanx

 

I've noticed a difference in every car I've put one in either with the acceleration or MPG. Just make sure you get one that seals well in the air box.

 

thanx todd howabout the K&N in ur hemi was that accel. or MPG ?

 

I can't really answer that question honestly since I purchased the filter and installed it on the way home from picking the truck up. If it gives a couple HP, you probably wouldn't notice it anyway compared to the power the Hemi already has.

 

I've been thinking about getting a K&N filter for mine but I'm just wondering how good they really are.

Took mine out and went back to stock Purolator. Had a pretty noticable hesitation off the line.

 

I have had a 318 and a 360, both with stock air filters, and K&N on stock box, and with K&N FIPK. The 318 has a decent difference with the K&N and even more with the FIPK. The 360, however wasn't decent it was much better then that. The 360 is STARVING for air and with the K&N there was a noticable difference in power and with the FIPK the power and mileage was more then just noticable. My opinion is, if you have the money get the K&N FIPK... if not go with the K&N filter in a stock box.

 

I've put a K & N in every vehicle I've ever had and you just can't beat the obvious advantages of a oiled filter to stop particles entering the engine as well as the increased flow of air. Not to mention you can clean it and not have to buy another air filter again.

I use the FIPK in my Hemi and I love the sound!!! and the increased throttle response.

 

thanx guys

 

I just purchased a FIPK K&N for my 04 Hemi, but am reading horror stories from other members about lover HP and torque.... Should I be worried?
