A little pricey but they look good!


Thanks…seems like I read someone did a few dyno pulls years ago and found the K&N filters very restrictive, You would think someone would make a less restrictive one, more like a flame arrester and not a filter, there’s not much dust out on the water

Eddie Young rebuilt a motor for me and took the filter particulate out and welded in a metal mesh on a blown 540, looked cool as ****!

That AZSM FL is a GOOD piece, on a stock 500 I see 6 to 10 hp gain on dyno taking the stock FA off, on a modded one its much greater. I dont remember the difference off top of my head but if memory serves me correct on a 620 hp modded 500 efi the azsm posed very little hp drop, Smitty
