I used this in a '96 Miata. The difference in acceleration is noticeable. K&N claims on their website how much power to expect, but they don't have numbers for my car. All I can say is "wow!" Note that due to the factory air conditioning in my car, routing the air hose from the air intake to the air filter area was a big hassle, but it was worth it.
