The Delicious Tuning YELLOW OEM+ Coil Packs are a great replacement to the OEM coil packs if you are looking for improvement in response, smoother drivability or just need a solid replacement coil due to age. We have tested the coil packs over on various development cars around the world, logging track miles, dyno pulls, drag strip passes, and daily driving miles in hot/cold conditions. If you have 100,000 miles or more on your coil packs, we highly recommend changing them.

- Forced Induction Engines

The increased discharge current, output voltage and longer discharge time of spark energy to the plugs offers a more complete burn, and smoother running engine. The higher voltage and longer discharge time allows spark plug gaps to be more easily maintained while helping with complete the burn cycle on high horsepower applications in all conditions, from daily driving, drag strip passes and extended track sessions. The combination of durability and stronger discharge current provides a more consistent combustion of the fuel mixture even under extreme conditions.

When To Replace Coil Packs

80,000 - 100,000 miles or
8 - 10 years of age
