## Description

ACDelco GM Original Equipment R45TS Conventional Spark Plug

Review: These are the best plugs for my 1993 Chevrolet k1500 with a 5.7 liter. I run a little bit of advanced timing causing a lean burn. Other brands will have the strap close as they get hot. These plugs with a higher nickle content will run 25k miles and still have plenty of electrode left. And the gap actually still be in spec. A few other brands I have tried get to about 10k before they are closing up or electrode eroding in my setup. Keep in mind I'm not running a hot rod. I'm running a 1993 TBI with over 200k. Its a little old and a little tired. Its not worn out by no means, but it's bone stock and that was always a mild motor setup. Put 30+ years on top of that I promise you its not burning any tires. But it loves these plugs and I'll keep using them. And at a few bucks a pop they are a bargain.
Review: Install the SP a couple weeks back . I feel my old truck is running better
