NGK # 3186 G-Power Platinum Spark Plugs TR5GP - 8 PCSNEW

My truck runs way better now that I replaced the spark plugs

I only run NGK plugs in all my vehicles and motocycles, Side by Side, and power equipment. They last and are always top quality. Price was reasonable shipping was on time easy peasy!

I needed to replace the plugs in a 5.3L Trailblazer. It's not bad for most plugs, but the #2 (passenger front) needed some special handling. To remove it, I used a normal 5/8 spark plug socket that has a 3/4 hex on the rear, then a short 3/4" socket on a flex head ratchet. To install it, I used a short piece of 3/8 fuel line over the plug to install it. I wasn't going to take the upper control arm off for a spark plug change. For the other three on the passenger side, I jacked the truck up and removed the RF wheel. I did not remove the inner fender.My old plugs were fouled and this had made problems with the wires, so I replaced everything and the truck ran much better.

put these in my truck and runs better than the $10 ea plugs the auto parts said would make it run better

I like that they were actually gapped accurately and not at all a bad price for the quality

As described good spark plug

Nice fit Chevrolet 5,3 2011

Worked great.
