So far better than the plug that came with the engine which lasted way longer than I expected. Good price to.

Jeremiah SensingVerified ownerMay 31, 2017on ProTek RC T4 Hot Turbo Glow Plug (.12 and .21 Engines)

These glow plugs are great quality, I get a lot of life out of them and they idle forever in my Reds R7 Evoke. Not a single complaint.

What reviewers say

Four of five reviewers rate the ProTek RC T4 Hot Turbo Glow Plug 5/5 and report good durability, reliable idle and hot-weather performance, and value compared with stock plugs; one reviewer used it in a Reds R7 Evoke, another in an Inferno MP9 TKI4 with a Trackstar engine. The one dissenting 1/5 review, from an unverified buyer, reports the plug working for about 15 minutes before glowing weakly, although the glow ignitor tested fine, and compares it to a Samurai P3 plug with the same problem. Reviews are few and the single negative report is not verified, so the overall picture is limited.

  • + Good durability
  • + Reliable idle
  • + Performs well in hot weather
  • + Good value compared with stock plug
  • − One report of glow failing after about 15 minutes
  • − Limited number of reviews
