Just curious if anyone is seeing hp loss.. I just read an article over at .com saying they experienced 5-10hp loss with a drop in K&N.. I certainly didn't experince any loss in power when I had my drop in filter on, but I shaved off the airbox. Anyone have numbers to prove that wrong?

 

no dyno sheets handy but

@1700mi 1st dyno pull ever 102degree outside
216/189tq

@2250mi spectre uni air filter no lid on box 99 degree
219/191

same dyno

and the numbers were high/low all right around those figs
i averaged them all and came up with the numbers in my sig

my highest run ever was 223.2 and 192.1 tq

so my 218.4that i claim has been average with 6 dyno runs so i feel pretty confident that that is my average whp

 

If the non-direct fit K&N was used in a stock airbox I could easily see why there would be a HP loss. But if it is put on a cut airbox I don't know how it could make you lose HP.

In the stock air box the filter you need to make work is way to big, the stock filter and drop in K&N has all 360 degrees exposed in the box.

 

I'll tell youy this much if it rain out side and I take my car out into the weather not even going into a puddle or anything my car pulls timing . How can i tell you say because every time it rains the chaeck engine lite comes on and the amount of psi's i can hit drops off 2-3. Its gotta be the freakin maf it's so finicky.
