Are there uprated 1.9TD glow plugs?

Hi just a question for a friend, is there such a thing as a higher output glow plug for the 1.9TD? I would have guessed the guys running a lower compression ratio would be running them already if there was, but I had to ask to make sure.
Thanks!

Red hot is red hot !
If they are new and in good condition and the battery has full voltage I doubt they can be improved much, maybe just to heat up faster but more current drain and then they'd overheat?

I don't know, the TDI plugs and the PD plugs are both hotter and faster than the older glow plugs so something must have changed. The TDI plugs are White hot.

Yes white hot!
Maybe smaller gets hotter quicker...

I have no idea. The PD glow plugs don't take kindly to being dropped, shaken or stirred before installation is all I know (while ours the older stuff seems to be a bit more robust). Not something I want to deal with. On another forum I visit a fellow got a free engine replacement due to a plug braking off after installation by the dealer. Sounds like loads of fun.
If anyone does have a known upgraded replacement part number that would be great I don't have an IDI and my cousin isn't going to know exactly what he's looking for either.

Bosche is probably the best.
Grounds are REALLY IMPORTANT too. A big fat wire from the negative terminal of the battery, to a trany to block bolt will do wonders for cold starts. Both the starter and the glow circuit are big current hogs. Bad grounding with affect both significantly. Especially because they're both opperating symutainiously on a cold start.

Cool thanks for the tips
I recall reading somewhere there are "fast" and "slow" plugs for the older IDI's would there be any advantage to using the fast plugs with the guts used to drive the slow plugs (Which I'm not even sure of how works on the IDI's on the TDI the computer tells the glow plugs how long to go based on several factors).

A slow glow relay with fast plugs will come to grief quite quickly. The glow plugs will burn out.
Keys to success: 4 good glow plugs, a good relay, clean electrical connections on the glow plugs, glow plug buss bar to harness, glow fuse, and good grounding on the engine.

That's what I thought might happen
I guess the TDI plugs are more tolerant to that sort of thing (I've got my glow time/tolerance increased a bit over stock via vag-com as I as having some issues starting in the 5-9C area where my car wasn't activating them at all). I'll pass the suggestions along

Can anyone exoplain briefly them hwo the time thing works with the relay, or is it all done on temperature - can see a timer anywhere? Thanks

What about the "dual coil" plugs I see on Ebay? Supposed to be a fast heat-up coil that switches to continuous duty after it heats up. Sounds like a great concept.

That's exactly the sort of thing he's looking for, now I have to do more searching lol

Well,... Share your results if you go to these plugs.
From my experience, the Bosch plugs work great, if you have all the other glow system components working correctly.
And I sincerely doubt that Bosch would blow off upgrading their product offering if there was truely a break through in glow plug technology:
