I used one of your BG kits on my 1998 F-150 with 179,621 miles. The kit consisted of BG EPR® Engine Performance Restoration®, BG MOA®, and BG 44K®. I got the engine warmed up, pulled the plugs and did a compression check. Then I re-installed plugs, added EPR® to the oil and ran per instructions, changed oil and added MOA® and ran for about 3 minutes. Removed plugs and ran another compression check. I could not believe the difference! I even checked it twice to be sure. I had an average increase of 20 psi per cylinder. I am very pleased with your products.
