EnsunDRX00059 Diesel Glow Plug - Fast Start Dual Coil - Compatible with - 1997-2004 VW 1.9 TDI (Pack of 4)

Works fine on 03 vw jetta TDI 1.9 engine

These looked identical in size to the Bosch plugs I removed. Two months in, and it starts reliably. Can't complain.

I was skeptical but actually my car is doing really good after 3 weeks even! The old vs new2003 TDI Jetta

Once I hauled the old ones out, a little antiseize on the threads and these went right in. Jetta starts great in the winter. Would recommend getting the glow plug harness at the same time. My old one was crunchy and I hated to reuse it.

The fact that 3 of the 4 went bad buy now has me puzzled. Now I'm asking the question do I buy them again?

I'm very surprised I got a part off Amazon that works.

I was skeptical on buying these, but it seemed like everybody did well with them. I bought these ahead of time so I had them when I started putting my engine back together. I finally got around to installing them and not even 1000 miles after install. One of them completely failed. Unfortunately the return window is closed and there’s no way to contact the seller. So unfortunately, I’m stuck with a defective product that I can’t even get replaced.

Put them in my son's 2002 VW Golf TDI and they work great! Absolutely no problems!
