Review on Straight Ignition Lincoln Mercury Compatible by Paulo Heisler

Ordered this morning and received this afternoon! I installed them tonight and WOW! Huge difference! The response of the truck is excellent, the gas pedal becomes sensitive. Runs like new, you can feel the power of the V8 again with 138,000 miles. Let's see how they hold up over time. Just thought I'd leave my review again to let others know that this product worked for me and exceeded my expectations! A quality product that won't break the bank! Keep it up guys! Update 07/11/2019: Three months ago, after about 45,000 miles, an aggregate failed, causing my truck to stumble and jerk. I had to tow my truck home and it's good that I kept most of my old original Motorcraft spark plugs which have already clocked up over 135,000 miles. I replaced the defective unit with one of my old motor boats to fix the problem. Let's see how the others hold up. :-(
