Review on 🔥 NGK 3403 G-Power Platinum Alloy Spark Plug TR55GP - Set of 8, Brand New by Joseph Elvis

I've been a fan of NGK for a long time, Denso too. But I chose NGK Platinum for my (new to me) 08 f-150. It's a 4.6 V8 so the plugs are normal but the larger V8 has crappy plugs with a 3 piece design. So glad it isn't. If you make spark plugs on this car and then change coil packs, you can find them cheap here. Since you're going to be climbing into the engine bay and spending some time there, just replace them. And when it's done what difference does it make, I can't confirm the gas mileage but I know from past experience these plugs help. In terms of performance, this truck just rocks. step on the gas and wow. I'm glad I did.
