Yeah, I heard that too. I might spray-paint them or just reheat them when they start looking dull.
Bet your miles per gallon will improve too.
Careful, you might blow the motor with all that extra power.
Depends on where you ask. Here, a million. On other forums? Negative horsepower, lol.
Nice! Where’d you find those cup inserts? I’ve been searching everywhere.
At least 13 horsepower and an extra 3.2 miles per gallon, easy.
