MPT IS THE MVP

I needed to replace my plugs badly. They were causing a nightmare with misfires. I ordered these yograded cold plugs and they solved the problem. MPT is the real MVP because my phone had shipping info saved that was out dated and incorrect. Simply I gave MPT the wrong info and they fixed the order and sent it to me after the fact.

Spark Plugs

I cannot say enough great things about this company. I ordered these plugs for my 2016 3.5 and when they got lost in the mail, MPT stepped up and replaced my order without hesitation! Hands down one of the best Customer service moves you can make. The plugs work perfectly and perform just like the description says. Buy with confidence from MPT. I've been tuned by them with complete happiness and all my parts come from these guys now. Thank you!

Great product from a great company

Plugs shipped fast and cheaper than an auto parts store. These are great for peace of mind especially if you have a few upgrades to your vehicle.

Good plugs

The plugs to go with if tuned. Checked the gap and they were all in spec. (Always check the gap) Probably the least inexpensive you'll find and fast shipping.
