I had a blitz drop in. It's sitting in my closet because it did absolutley nothing. I replaced it with a blitz sus intake. That intake just makes cool noise.

If you just want something that you can bolt on and have some kind of gains, then STI is a way to go!!!!!!!!!!!!

^^ I Agree ^^

Leaning out your cylinders does make more power but trust me .. Its not power you want. Save your $50 for now and wait until you have engine management or a reflash.

I seriously doubt a panel filter would lean out anything. It's not a big improvement over a stock filter.

motor oil is for lubing the engine, heat dissipation, and catching particles so they get stuck in the oil pan. I still wouldn't use engine oil on an air filter tho.

FYI - I just took my 2003 wagon to get it's 30K service and the dealer said my MAF sensor was dirty and gummed up with oil from the K&N filter.

I was getting an intermittent CEL and I guess that's what was setting it off. I didn't know about the history of the k&n and the problems it caused on the wrx MAF sensor so I did a search on i-club and guess what? I'm not the only one who had a problem!

Do yourself a favor and do a quick search... the dealer replaced the k&n with a new paper filter and I just ordered an STI filter. More flow without the oil.

I've used k&n's on all my previous cars/trucks with no problems. But it's just not the best option for our subies.

cheers
