39,000 mile spark plugs 1 bar tune
There has been some discussion about changing your spark plugs sooner when you have a tune on your car. Here are two pics of the plugs after 39,000 miles with a 1 bar tune. The gaps on the plugs have increased about 30% from stock. color is good. These plugs are the Beru brand and were in for 39,000 miles. Overall, they appear in decent shape. The only thing that caught my eye was the increase in gap. The car started fine and ran well. Hit 150 mph with no issues.

Those plugs look just okay to me. They look done.
This is what good plugs look like. 30k miles, no tune.

all the plugs pictured in this thread look bad IMHO...I'd be aiming for half those mileage intervals

My car ran perfectly with plugs that some here think look bad.
It is how plugs with 30k should look.
