Gapping spark plugs

[tico481]

What does the gap need to be when I put in new spark plugs? I just bought some new ones and it said on the package that I need to set the gap. I have the tool to do it but I just need to know how big the gap needs to be.

Your owner's manual has the proper gap. The data plate in the engine compartment also has the info.

i just buy the ones that are right to begin with

Good point. When you but the proper ones, gapping is usually unrequired!

I thought you were suppose to double check the gap before you install to make sure they wern't bent during shipping?

[tico481]

I would check my owners manual but the previous owner of my car didnt give it to me with the car. Where would I find the setting on the engine compartment? ghead

But yeah, i bought the ones that are for my 325is. So does this mean I dont have to gap them?

Always check the gap! I have found that with the right plugs, the pre-gap was damn accurate!

right choice CiscoKid. not to mention the trouble of having to perfectly gap four ends of a +4 plug.
