Hey guys, i have been doing a ton of reading, lots of info available. Still plenty of controversy. I have a 95 Mustang that i will be fabing a 4in intake pipe setup for. since i have an electric fan and cowl hood, under hood temps and "fan wash" are really not of concern. It is a high 10/low 11 second car Naturally Aspirated, redline of 7k, maby 7500 if it keeps making power that high. it needs a decent amount of air. I plan on a 7 to 9in conical with a 4in intake inlet. I like the idea of the dry filters rather than the oiled. Cleaning time/work is not of high concern. The car probably wont hit 5k miles a year. Mostly highway driving and drag racing. Southern Louisiana I was at the local parts store looking for 4in couplers (which they didnt have) and i looked at the spectre filters and since they were packaged, it made it hard to look through. the view angle i had didnt show sand size holes. the whole reason i am digging deep into this is this: i bought one of those bbk cai and the filter didnt come with oil and i never thought twice about it. well sure enough it needs to be oil. i held it up to the light and i saw pin holes in it Price isnt a big concern. Quality filtering and enough air flow is what im going after. What are the Positives and Negatives of these brand filters: K&N, AEM, AFE, S&B, Spectre, or Amsoil On a side note: spectre parts seem to be cheap made parts, thats in my opinion. I have seen what aftermarket filters have done to turbo blades on a diesel. either from lack of maintenance or bad filtration or maby both.
