Even after reading tons of reviews I was a little skeptical, but not anymore! Noticeable improvement in torque, couldn't believe it and the sound is great.Installation took about 45 minutes and I'm no mechanic. Two words of advice. The original mounting plate under the factory air cleaner box comes out and also the factory flexible breather tube comes out and is replaced by the supplied tubing. I could not be more pleased with the product and performance. I'll keep my eyes on the mileage.
