There was no significant reduction in ET for me.I’d rather run a filter.

ALL filters have some restriction.. its a matter of how much.. if you race at a track thats dirty then you need a filter to keep the dirt out of the engine.. I dont use a filter but thats me.. K&M does have a bit more restriction than some of the other filters proven on flow bench

does any one run a air filter like a K&N drag only car did they hurt your ET K&N makes one for my hood scoop before I buy one just want some more info I know some Stock Eliminator guys that run these filters and don't remove them for heads up runs. I ran a K&N oval filter and the filter lid on my Stocker zero performance difference. If you are running a bracket car, what difference does it make if it slows the car a couple of hun. I would rather jet for it and keep trash out of my engine.

I won't race without a filter. I have made test hits with the scoop and filters off and there was NO change in my AFRs.
HEMI-ITIS has no cure.
My condition is fully BLOWN!!

No way I'd run without a filter. Have seen too much junk, whether it be a rock, bolt, or rubber, fly back, and hit the car. Wouldn't want it going down the carb as well.

I have use and tested K&N filters and the K&N top filters, two motors on two different dyno lost 8 HP on the dyno. My old race car went .2 ET quicker and .23 MP in the 14 mile with the top on versus with out it off with a six pack type scoop with the lid almost touching the back of the bottom edge of the scoop. I haven't race a bracket motor with out a air filer on it since 1970s

Biggest K&N I could fit with no oil. Just trying to keep the big stuff out. I think it actually helped the car by straightening/smoothing the air in the sealed scoop. Made the cylinder walls and rest of the engine look noticeably happier
If the results don't match the theory, change the theory.
