This simple, bolt-on advance kit advances the timing 5 degrees. With stock engines with stock compression ratios, there is more power everywhere. Part throttle power is better – helping corner exit speeds. Improved in-town drivability and quicker warm-up.
Absolutely REQUIRES an AIR IMPACT wrench to install – If you try using the puller without an impact you WILL strip the puller and the ruin the puller threads in the flywheel!
