Hi, has anyone tried o'donnell plugs in a reds racing engine, specifically a .12 M3WC, used them in my maxpower engines and they worked fine, even better than the nova plugs, just not sure if the thread is ok to used on a reds?


Thanks
Rias

straight from the man himself you're good,

Yes they will work fine, though they aren't the best plugs around. Find yourself some LM plugs (Sirio, IDM, etc.)

Exceed and os are also better choice

Thanks for response guys.

Hi guys, just some feedback from the odonnell 77t, started off yesterday with the reds plug that came with the engine, started leaning out the engine with breakin done, switched to the 77t and the engine felt a bit more responsive, went through about four tanks with the odonnell and switched back to the reds plug, engine felt lazy on bottom, all this without changing the tune, so im gona stick with the 77t in the engine.

yeah the plugs are great everything is a lot crisper and tune is easier

if you want to we use 99 in1/0///1/8 and they last for ages and never/never /drop filaments into engine like our nover plugs did we used 1 plug for nats last year
