Gapping spark plugs

[Specialedition]

DYNO RESULTS.

they may be pregapped from the factory, but it doesn’t gaurantee them not being damaged/bent during shipping. Sometimes they don’t have the cardboard sleeves to protect it.

so yeh, you always need to double check the gap. Don’t forget to anti-sieze the threads too. you wouldn’t want the plugs to get siezed in the block. this usually happens to high mileage cars though that never get a tune-up.

indeed i did this already, although im a nazi when it comes to my cars maitenance, so no problems here
