Spark plug NGK or OEM Volkswagen

NGK Iridium, it’s what I get about everytime.

Recently got the following parts: Racingline VWR Springs 034 Motorsports strut mounts, new bearings and bump stops Rear strut mounts with new hardware and bump stops Deautoled LED license plate OEM Autodimming rear mirror with wiring harness APR boost tap NSP boost gauge with vent Hella oil level sensor Oil pan w level sensor European Headlight Switch APR Coilpacks Spark Plugs NGK BKR8EIX R LINE CENTER CAPS

Just changed mine out for the second time 2012 w/ 172k. Misfire engine code. NGK iridium. Getting 10 more mpg. Best 50$ I’ve spent in a long time

Iridium will last longest. Grab them if you race or run the piss out of that bike but for all intents and purposes a plain old NGK is plenty adequate for everyday riding and then some.

Ngk have been pretty reliable motor craft is pretty good too but I've seen good life spans for both.

Very broadly, only use NGK, Denso, Bosch, or Champion.

according to my halfords e- receipt i last used cr8 iridium plugs, no complaints here.

NGK all day, compared to all others they’re just made better, I bought Bosch platinum for a VW and the OE came out were NGK, after 50k they were still visually a better manufactured plug. Example- the plating on the Bosch threads was rougher.

I've seen with a digital tachometer a 1,000rpm difference between a laser brand spark plug and the oem ngk spark plug in a chainsaw. So for me it's what the oem uses is what I put back in.

I've had my 2006 Audi a3 3.2 quattro dsg for 5 years now, and every year or so I will have an issue with a misfire on cylinder 6. It is always cylinder 6. I use the recommended NKG IZKR7B(7563) plugs. I often find that the cylinder 6 plug has a crack on the ceramic insulator around the electrode. On one of the plugs, half of the insulator is missing. Replacing the plug always fixes the misfire. I also noticed most recently when I removed the damaged plug, it was very hard to turn and some of the aluminum from the head has fused to the threads, leading me to believe that the cylinder is getting too hot.
