Hello all.

2010 Challenger SRT8.

Not very familiar with plugs. Is there a real difference in the stock ac delco and bosch plugs? I am buying my wife some tomorrow.

I bought some mobil 1 5w 30 high mileage for an oil change.....?

thx

 

Use OEM equivalent plugs. Autoparts store will be able to cross them for you. If it has high mileage, high mileage oil is fine as long as it meets the recommended viscosity requirements.

 

As long as the plug is equivalent to what the factory calls for: 5037404AA (current number SPLZTR5A13)
Also you have the wrong oil weight (5W-30 was for early non-MDS 3rd gen 5.7's) for that engine. 2010 SRT8 = 6.1 hemi = 0w-40. If you still have your stock oil cap it's on there:

 

thank you much.
