"I love the powder-coated finish and overall quality. I think a minor mod will be necessary to modify the installation to compensate for the slightly different location of the SVT throttle body when installing on a Focus with the Jackson Racing Supercharger. Maybe K&N could supply an extra length of flex hose." —Coleman S from Los Alamos, NM bought a K&N 69 Series Typhoon Intake Systems for a 2004 Ford Focus.

Jet Performance Power-Flo Mass Air Sensor

Great bolt-on upgrade

Sensor did what they claimed it would - improved low-end power. My HHR is 2.2 l & was very sluggish at low RPM, even considering it is a 5-speed. Car has noticeable improvement in accelleration, a big plus in traffic driving. RE: mileage improvement claim - marginal at best(ignore this part if you drive a Tahoe)Hwy is now 30.2 up from 29.9. Overall, is worth the cost & requires very little effort to install. View more reviews...
