I installed this on
Honda Civic

Review
Got this for free from my friend who switched to riding, giving away most of his high performance items. Used it on my ride for the challenging track, and the results were astounding! Ensuring the engine performs at its optimum and being pushed to the limits, the power delivery to my wheels are fantastic. Using great traction tyres, pickup off the line would be like dropping down the track from the roller coaster. The adrenaline it gives you is just WOW. Would definitely recommend this to the trackers, the aggressive drivers, or even those who just love comfortable, smooth drives.

What I like
Provides the requirements for my engine to perform at its optimum!

What I do not like
They are expensive.
