TRQ parts saved me $$$!
After changing the coil packs, plugs and wires with the TRQ set from A1AUTO I was extremely happy with the money saved and the performance so far! The A1AUTO videos on youtube gave me confidence to maintain my H2 on my own so I decided to use the same parts they were using from TRQ. So far so good.

I'm very pleased with this well put together kit! Everything is of very good quality! I think that the red looks really cool too!! If you were to purchase all 8 ignition coils separately, you'd easily spend over $400!!! Truck runs better, smoother, with improved crisp throttle response!! I highly recommend this kit from 1A Auto!

One plug misfired within 50 miles and a plug wire pulled apart while changing plugs. Had to buy new plugs and wires. Hopefully the coils hold up.??
