1. no u dont all cars can handle slight changes if u put a turbo on then yes
2. show us that 4/5 horse power
3. got turbo?
4. or if u got a wustang
5. This idea has been going around for a long time. Look up K/N on the blogs and check out the opinions. You are supposed to add some sort of oil to the filter - this oil is sucked into the intake and coats the MAP sensor. K/N has heard this theory and disputes it - of course they would. I stick with paper filters - just change them routinely.
6. Need ECU recalibration or standalone chip to fully utilize air/exhaust upgrades.
7. Really? Got proof was thinking of getting one soon.
8. You're right every vehicle I've seen with a K&N has fine dust inside the intake plenum.
9. 1 horse power and a shit load of micro particals inside the engine lol...
10. take off the stock air cleaner and go get a short ram cold air intake from autozone and put it together
11. KN filter is reusable, having said that, everything has its life, once it gets dirty, you can wash it over and over til it can't be wash again, like 100,000 miles but still worth 40 bucks
12. K/N air filters wreck the MAP sensors.
13. with carburator it would run lean, but EFI with oxygen sensor, no problem.
14. I agree. Total pieces of shit. I tried a few K&N filters on a few muscle cars I own.....no performance gains, just overly dirty filters.
15. eww a 96er. do me a favor. next time your driving, put a brick on the pedal and aim it at drainage ditch
16. +5hp and run too lean.
17. a gain of 3 or 4 horsepower is like taking fly poop from pepper
18. 3 or 4 horsepower gain is like taking fly poop from mpepper
19. I THINK THAT BIG THING HE WAS SAYING GOES BEFORE FILTER, I THINK HE IS RIGHT +HORSE POWER
20. HA HA HA 
21. haha you can try that mate! :)
22. are u being serious or was that a joke?
23. k&n suck they make no difference at all, 1hP my arse you will gain a dirty ass engine is what you will gain
24. stfu dude
25. or you can just get a cold air intake and not be a poor bastard

99% of modern vehicles on the road have some form of sound baffle. Car enthusiasts love to hear their engines but the masses don't so a sound baffle is installed in most vehicles and even in a lot of performance cars. Let those few extra horses lose and locate your sound baffle and huck it in the trash!
