They are junk. Get the normal plugs for your truck.

Thanks. I can use champion rn11ycc's. But why are the bosch plugs "junk"?

They have a super thin center electrode that burns away too fast, and then you'll have misfires.

Good plan. The GEMS 4.0 engine is not very sophisticated, so putting fancy spark plugs in it seems mismatched. I have run the Champions in my D1 for years with good results.

Champs with a wider gap. Change them a little more often.

Took my +4's out (installed when I bought it) and put in NGK V-powers.

how wide a gap ? just curious

spec is 0.040"

Adjust gap to 0.045 - 0.050

Honestly, I've done both. Never noticed any difference: performance rofl, mpg, or otherwise

I used champions RN11yc4 and new wires; cleared po3oo and p1316 codes-all is well.
Spec. I had for gap was 0.035 - 0.040 in , so I used .036.

I usually go 0.045 to 0.050.
