NGK BKR6E or BKR7E?

ppeters914 · Nov 23, 2020

2008 Boxster RS60 (3.4L, 41k miles)
"Check Engine - Visit Workshop" light came on.
Stopped at AutoZone and had them run scan. Error Codes:

P0300: Random Misfire Detected
P0302: Cylinder 2 Misfire Detected
P0303: Cylinder 3 Misfire Detected

Plugs past due for replacing, so went to order. But what to order?

Pelican says: NGK BKR6EKUB (NGK #7969)
NGK and NAPA say: NGK BK7EQUP (NGK #4285)

Any idea why Pelican would recommend the hotter plug?

Thanks.

I would be inclined to listen to Porsche parts numbers and you can always verify with what is in your current car.
Bosch also makes OE plugs for the car...,

If you have misfires in one bank, do check the ignition coils as they fail around this age.....

I replaced the plugs in my '08 Cayman S with Bosch FGR5KQE0. No issues....
