Air filter?

I have an 84 rs v8(duh) 305 and i was curious how much horsepower a K&N high performance rechargable air filter will add by itself. I've been told numbers as low as nothing and as high as aobut 15. BTW I'm carbed not injected. Thanks in advance.

I really doubt that a K&N alone would do that much on most vehicles. A few years back I took my air clean totally out and took a quick 2 mile or so drive around. The car pulled SLIGHTLY harder at almost full throttle. I didn't really notice much of a difference with no filter at all, so I'd imagine that a K&N would have been a waste of money for my car. Every engine handles mods differently though.

My roommate swears that the K&N makes a noticeable difference in his 91 Camaro Z28. My cousin had a 91 Z28 also. He used to use a K&N filter for couple of years and said that it helped just a little. My cousin stopped using the K&N after he went to UTI in Texas. He told me that he thought that the K&N was making his intake look a little more dirty.

Most of the parts in a car work as a complete system. Usually changing just one part (such as an air filter) doesn't make much of a difference if the rest of the system isn't upgraded also.

3-4 Horsepower. If you want some more power just get headers or somthing.

or a blower

yeah, put a blower on it :) i would say a safe bet for the filter adding power, might be 5hp, to possibly 10hp.

five at the most, definitely...

it will improve gas mileage for sure.

I recently put a k&n on my 95 Z28 and I really could not notice a differance between my old fram and the k&n. Don't get me wrong though a k&n will held your motor breath easier just for the fact it lets more air in.

As far as the blower I don't have that kind of money, and I plan on headers but I've heard they are fairly difficult to put on. How hard is it? Is it worth paying a mechanic? thx

i dont know about you v8 guys but the headers i put on my car werent difficult to put on at all, my gas mileage has gone to piss since i put em in though...

what kinda car do you have???? must not be a camaro, headers are a bitch in F-bodies, unless you can put em in through osmosis.

well i used osmosis to study in high school so i was pretty well versed in how to use it, i just applied it to my camaro and what do ya know, the headers just fell right on...

lmao

my friend put a k&n on his s10, we noticed a little difference, it didnt take as long to get up to 100, me i havnt had really much experience with them all tho i had one on my bronco (carb) and i didnt notice a difference between that and the other air filter i had on it, maybe it jus depends on the vechical
