I've changed my spark plugs three times, always with the Bosch Iridium, never had any problems. Pre-gapped, takes me about 30 minutes from start to finish. Lasts me about 90,000 miles.

Pros: no problems, lasts long

Mileage: 144840 km

I've recommended many times to toss plugs and replace with NGK (you can read about my experience in prior post). You have hopefully educated newbs to follow you.

Pros: replace with NGK

I pulled Denso plugs out of my truck and put NGKs in. Is there a difference? Maybe... But experience with Japanese industrial equipment says that Japanese engines like OE ignition components. NGKs are cheap and readily available.

Pros: cheap and readily available

Vehicle: Nissan
