Owner reviews for spark plug

Autolite or Brisk plugs with stock gap.

I have a 05 with Edelbrock SC, 11 pounds of boost, and E85.

I use NGK on my supercharged Roush. The recommended for supercharged engines is 28 to 30k miles. The only thing that you need to research with the e85 tune is whether or not you need a hot plug or a cooler plug. Roush calls for a cooler plug

Some weekend progress after work, got the plugs changed out and fresh air filters are in.

Yes definitely get the original OEM Denso plugs and be really cautious of anything you purchase off Amazon a lot of them are counterfeits. You can either go direct to the Toyota dealer or you can go to your local parts store like Napa and just make sure you order the correct Denso Plug.

The plugs look really good pretty even color across all of them no major carbon buildup. Wear on the plug seems typical for 100,000 miles.

I actually had a generator that would take 4-6 pulls to start with the "Torch" brand sparkplug, but starts in 1-2 pulls with an NGK.

BP7ES is what I have in my Wgen. Cranks 1st turn over everytime now since I switched and instead of rolling over 10-15 times with the crappy Torch plug now takes 1 second.

Quicker starts is a result...I just followed the crowd on this one and from my days at NAPA, i was a NGK and Bosch spark plug fan back then.

Try changing out the rs7 plugs and go to NGK R7437-9 or 8. I’ve heard the RS7 plugs having issues in these cars.

My 2000 with California emissions (regular cat and then two pre-Cats at the exhaust headers) would only run properly with the oem spec NGKs. Threw Bosch in their once and it ran terribly.

Iridium plugs suck on fords.
