Anyone got good recommendations for good glow plugs,, I have blown out the few Traxxas plugs I have, looking for a tougher plug with a little more life to it

The O.S. LC4 is a direct replacement for the 3232X if I'm not mistaken.Anyone got good recommendations for good glow plugs,, I have blown out the few Traxxas plugs I have, looking for a tougher plug with a little more life to it

In my 4tech 3.3, (Highly modified engine) 12,000 squish band height, timing, opened up boost ports, narrowed con rod, skirted piston, drilled through crank weight "To throw fuel up into the case", stuff like that.Anyone got good recommendations for good glow plugs,, I have blown out the few Traxxas plugs I have, looking for a tougher plug with a little more life to it
Nice,, will be totally looking into those plugs,, Thanks for the feed backIn my 4tech 3.3, (Highly modified engine) 12,000 squish band height, timing, opened up boost ports, narrowed con rod, skirted piston, drilled through crank weight "To throw fuel up into the case", stuff like that.
Anyways, I ran 30% and 40% FHS Oils Red Max fuel and blew OS max plugs all the time.
I decided to run the K&B long plugs with the 30%, and for 40% I ran the K&B short idle bar plug.
Idle bar plugs have a bar that goes across the bottom of the plug and protects the coil. With the 40% nitro I used the short idle bar to keep the coil intact due to the higher rpm of the extra 10% nitro without having to re-shim the motor's squish band.
With the 40% if I run a K&B long plug, it would run just the same except it would compress the coil, but never suck it out or kill the engine. So, I went with the short medium Idle Bar plug for a few different reasons,
1) To give me a little less compression and save the coil and the idle bar helped from lowering the compression too much.
2) The idle bar helps keep the coil glowing hotter as it kind of diverts the updraft from the piston moving upward, so the coil glows hotter and doesn't get pushed up into the plugs body "Compressed".
Other brands have idle bar plugs, but I use the K&B plugs because I can file a small clean spot on the bottom of the blackish colored plug body, make a few high-speed passes and pull the plug and look at the clean filed spot to check for "dry/burned lean" run or "Wet/clean rich" settings.
Usually when an engine is eating the coil, it's from a too lean setting, or too high of compression for the nitro content. "In layman's terms" those are the two common reasons a plug will blow.
This of course worked for me, and I can't say if it will help you or not.

here is a link to the mecoa plug page.Nice,, will be totally looking into those plugs,, Thanks for the feed back
Awesome,, Thanks!! I changed fuels to VP 20% and it roasted the glow plugs in just a couple of tankshere is a link to the mecoa plug page.

In the pic I supplied the top two plugs are K&B HP plugs, the bottom plugs are K&B idle bar plugs.
mecoa has a wealth of general info if you look around the web sight. Plus a wealth of parts too.
I have been using KB and HP plugs for 40 plus years they are robust to say the least. When I do use random OS or other plugs, they get mangled.Awesome,, Thanks!! I changed fuels to VP 20% and it roasted the glow plugs in just a couple of tanks
Have not had a chance to really check any of that yet,just got the engine broken in a few days agoI have been using KB and HP plugs for 40 plus years they are robust to say the least. When I do use random OS or other plugs, they get mangled.
FOX makes some really good plugs too, I think K&B manufactured FOX plugs too. Mecoa is K&B, Mecoa bought K&B a long time ago.
The 3.3 engines have varying squish bands (Sloppy work from the factory). I have had many 3.3 engines and they were all different squish band heights. If I remember right, I think Traxxas says 16000 "Sixteen thousandths" is what's recommended for optimal use and longevity. May I ask if you ever checked the squish band? And if so, what is the reading?
Like me at 12-13ish000th (Twelve to thirteen-ish thousandths) I'm doing that on purpose to build power and knew mangling plugs would be an issue considering the high nitro content I use.
(I run my 4tech in a huge nascar style loop) where I can get it up to speed and keep it at full throttle.
I found that between 14000th and 18000th the plugs lasted 20 to 30 tanks on 30-40% nitro (No joke). I run FHS Oils Red Max fuel.
Oh yeah, I forgot to mention, as far as cold and hot plugs go, I never worried about that, some do but for me it never really mattered either way. The differences weren't that great of a deal.
Have you checked your squish band height? It might be too tight. I don't think you're running it too lean so maybe your deck height is too tight.
Oh it's a new engine, new engines blow plugs, just part of the hobby.Have not had a chance to really check any of that yet,just got the engine broken in a few days ago
The LC4 is a medium hot plug just like the 2525x. Just FYI.O.s Lc3 works good too. Lc4 is medium, Lc3 is hot
