NGK SPARK PLUGS (USA),INC. (3346) BR7EF V-Power Spark Plug, Pack of 1

Great plugs so far (about 500 miles). Previously ran NGK TR6's in my GT500, running about 15PSI boost w/.035 gap. So far these seem to idle/run even smoother (but don't new plugs always run smoother, will have to update review after $10-12K miles or so... noting that I replace my plugs about once a year anyways, so I always go with the inexpensive standard plugs and not the pricey iridium).

Great product, especially for boosted cars via turbo or charger... best for 9-15 psi...

I thought NGK was the id of these spark plugs. Well, that was stupid of me. Because I did not mention the specific serial number of my outboard motor plugs. As it turned out, what they sent me didn't even have the same diameter as my existing plugs. My bad. Hoping you won't make the same mistake.

My generator works guess that’s what it was supposed to do

Good

Purchased for lawn tractors. Great quality and less expensive than at the big box stores

Runs great in my blown ls

To small to screw in and missing the small part that screws in the top
