Correct length plug wires
In an effort to "tune up" my Ford Ranger and address a stumbling (almost misfire) i replaced the plug wires. This didnt fix the problem BUT I did discover that my previous wires were mostly all the wrong length leading to a cluttered and awkward routing appearance. These new wires for 1AAuto were the perfect length and look great when Im under the hood

These are for my 2009 Ford Mustang V6 are they pre gapped?

This will fit the 4.0L V6 model only. This is just for the wires, the spark plugs will have to be gaped.
