We used to put Bosch W7DTC spark plugs in them. No gapping required, smoother idle, and they last 60k miles, maybe more.

Pros: smoother idle, long lasting

Cons: no gapping required

Vehicle: Volkswagen

Mileage: 96000 km

Part number: W7DTC

You can get NGK or Bosch plugs on rockauto for around $10. Not sure which was OEM, some like NGK for Mercedes in general but Bosch tends to be the OEM maker of plugs for MB.

Pros: plugs available on rockauto

Vehicle: Mercedes

If these are for a TJ (97-05) return them and get NTK (NGK). The 4.0 will not like anything else.

Cons: engine incompatibility

Vehicle: Jeep Wrangler

Yeah I own and operate an auto repair facility and refuse to use Bosch plugs because I’ve had a lot of issues with them in the past. Misfires mostly.

Cons: misfires
