Fantastic Upgrade for Auto Transmission!

After trying this Ignition Part, I've noticed an increase in shift precision and smoother performance. It was a breeze to install and definitely a step up from the factory module.

Pros
  • Improved shift precision and smoother performance
Cons
  • None found

Excellent 04 f150 4.6

Easy install, about 10 minutes. This element takes 4.6 in 04 f150 to the next level. Throttle response is great and you can feel the power. He recommended 91 pump gas for best performance and 93 for towing. I ran 87 on the first test.

Pros
  • Engine computer
Cons
  • Contact seller
