Night and Day difference!

Complete night and day difference between the GMS 4v Hot-Street Coil packs and OEM. I had a coil pack going bad but couldn't pin point which one, installed the GMS coil packs and WOW what a difference.

    Night and Day difference!

    October 08, 2012

    Complete night and day difference between the GMS 4v Hot-Street Coil packs and OEM. I had a coil pack going bad but couldn't pin point which one, installed the GMS coil packs and WOW what a difference. Instant grin on my face(and I swear the Pony in my grille was smiling too) the first time my foot hit the floor. This product has a great fit, produces a great power gain and is well worth the money! I definitely recommend this product for everyone.

    Hot street coils

    March 26, 2013

    i just installed these on my car ,took about an hour working slowly. the first thing i noticed was that the car had better throttle response,then when i drove it it felt much peppier & nimble. i got i just to nail it from a stoplight with tracion control off and it rev'd so fast it smoked the tire for about a block long,these things work good im happy with them.As far as the stories of them failing time will tell but so far no complaints,nice bang for the buck! thanks AM.
