Love your Product! This particular one went into my SS Monte. Instantly felt it to be more responsive, the same as my other installs. Incredible product. Thank you all, great job! Frank

Awesome filters. I have them in all of my cars. I run one in my 1983 El Camino and it made a big difference in gas mileage and acceleration .

I added this to my 1987 Monte Carlo SS Aerocoupe some years ago and noticed a power advantage right away.
