Order that went out for Holtz Automotive & Performance Engines this weekend. Really happy about how these turned out. Call Chase if you need some work done!

This tool makes life so much easier, vehicle came in with a P0021-73 (Airflow/Vacuum leak detected) code. Had it figured out in less than 5 min, new intake gasket and onto the next 👌

Had a cracked aluminum wheel repaired last night by Zach Frey and wanted to give him some recognition. He’s one of the few local welders around here doing aluminum work, and the repair turned out great. If you ever need quality aluminum welding, he’s definitely someone worth reaching out to. Thanks Zach !!
