I have four cars, a 67' Malibu SS, a 70' Baracuda Hemi, a 93' Mustang Saleen, and a 02' Focus SVT, all extreemly powerful straight from the factory. I was skeptical at first, but I put a K&N XStream filter in the Malibu and in the 'Cudda, a cone filter in the Mustang and a Typhoon kit in the Focus. On the Malibu and 'Cudda I immediately noticed more horsepower and a crazy kick in the pants feeling. The Mustang I super charged and with the addition of the cone filter it felt like I added an extra 4 psi of boost. The Typhoon kit didnt help the Focus' horsepower much except on the low end (which left a lot to be asked for) it added more than enough torque, in that little four banger Focus, all stock. Save the Typhoon kit I'm now running low 10's on the 1/4 mile.
