Performance Tool W38154 3 Piece Extension Review

This tool set simply couldn't hold up to the rigors OF everyday automotive use. After I put it to the test, I found the extensions to be weak and lacking in durability, which led to constant slipping and frustration during projects. The only positive aspect was the low price point .An overall disappointing purchase for any serious auto mechanic..

These are very handy for changing spark plugs in new OHC engines. They snap right onto all of my spark plug sockets. If you've done this job before, you know how frustrating it can be when an outlet gets stuck in a plug after a fresh install. The only reason I gave it 4 stars is because of the plastic button used to unlock the expansion. No problems so far, so don't let that put you off buying. This is a much better design than lock-in collar extenders which have been known to fall apart.
