I have K&N products on trucks that perform well for horsepower, but for my SS Monte Carlo, I honestly was pessimistic that it could also gain fuel mileage, and horsepower. It is nice to have a product that does what it says. I have gained an average of 4 mpg, with a gain of of 13 HP average.That is good medicine for a supercharged SS Monte Carlo. I installed with in 2 hours, at my own pace. It truely works.What more can you expect.K&N is a good company.
