its the race blend from oddonnel. ive used the MC-9 snce i started running my car. engine is .26. should i switch to a colder/hotter plug? the glow ignitor is still good, i used mine which has a beep tester that tests the glow plug's life, and i used my friends which he uses on his revo. i plugged my tester ignitor in mine, no beep. i plugged it on the revos plug, theres a beep. everytime i plug my tester to my glow plug im always scared it wont beep
