Hi guys, just wondering if in your experience the quality of glowplugs have much effect on operation? Is it worth spending the extra on genuine ones?

I bought some cheap ones, they lasted about 6 months. I'd never buy cheap again, I've never had issues with NGK stuff.

Got Denso off carparts4less. £6.96 each. Only been in 2 weeks so far. Hoping not to need another set.

Get Bosch, NGK or Nippon-Densu; this is a case of buy dear, buy once: buy cheap, buy every few months.

Haha this reminds me of a car that I fixed ages ago ref: spark plugs, the geezer I did it for was a proper Yorkshire northerner, and he asked me which spark plugs he needed to get, and I says " are they champion?" and he says " no ther're ****ed"

any who onto my point, I'm pretty certain that the genuine oem glow plugs are made by ngk, so there's no difference between those and a aftermarket set of ngk glow plugs, they even have the same part number stamped on them, the oem ones just have an additional vag number on them too.

And a few quid on the price tag I bet!

Actually no, you'd be surprised how reasonably priced some of the genuine parts are nowadays for the older models.

edit; ignore the last, I've just looked it up on etka, the oem glow plugs are Bosch ones and they Ada out £12 each, it's the spark plugs that are ngk oem on the petrol engines.
