have been trying to extract some extra power, without breaking the bank. so i read some articles of air filter size, all mine have the round 14"3" airfilters so i went up to 14"x4" and man did it make a big difference. the article i read was 14x3 was good for up to 400hp and 14x4" filters were good from 400 hp up to 500horse power, the 14"x4" wix raceing air fifter sure made a big difference in power.........
