I love my green filter to death, needs to be cleaned lol, but I absolutely love the sound. Everyone keeps telling me to get a blow off valve but the green filter is all it needs, more than enough intake noise and turbo flutter
Pros: great sound, love the filter
Cons: needs cleaning
Well even if you don’t take off the AirBox lid, the green filter is 100x better than stock. I personally loved Green over K&N because it’s bigger and green is fun compared to black. I have my intake lid off and hear turbo, BOV, and other noise. It’s great!
Pros: better than stock, great sound
I'm gonna guess it's like k&n or aem. I've got k&n without the lid and I get some noticeable intake noise and when I shift from inside the car.
Pros: noticeable intake noise
Green filter + no airbox is the way to go. It might be a little louder with just the filter, but im not sure by how much. I went years without the airbox lid, its all good
Pros: good sound, years of use
Getting 41mpg with a little help from K&N air filter.
Pros: improved fuel economy

IMHO the performance gains from the K&N are marginal at best, especially on a 1.8 litre motor. It's less hassle to just replace the paper filter element every year with a freash one than cleaning the cotton filter annually. the K&N will likely require eight years to get your return on investment. Besides it you live anywhere where it's dusty you going to be doing your motor harm... I read about farm trucks with these installed the puke their motors because fine particles are getting into the motor. YMMV.
Cons: fine particles into motor
I just did the switch to a K&N filter recently on mine. Did not notice any difference. I remember feeling a greater difference in my VR6. Maybe its the fact one is N/A and the other F/I.
Cons: no noticeable difference
Vehicle:
Audi S4
K&N filters are a scam. Anyone who installs them is a sucker. Anyone who recommends them is a rube who doesn't understand how their vehicle works.
If you care about your car, DO NOT install one of this shitty products.
THEY DO NOT MAKE MORE PERFORMANCE ON A STOCK OR NEAR-STOCK VEHICLE.
THEY ALSO DO NOT FILTER WORTH A CRAP.
YOU WILL NOT HELP YOUR ENGINE AND YOU WILL CAUSE EXCESSIVE WEAR.
Cons: scam, no performance gain, poor filtering, causes excessive wear

Thanks for posting this. I just bought a '91 MR2 and I've replaced all the filters... except this one... probably why the air is so bad.
Cons: air is so bad
Vehicle:
Toyota MR2
