🔥 Motorcraft SP-413 High-Performance Spark Plug Review

They arrived in original Motorcraft packaging and today I installed them in my 2005 Lincoln Town Car and my car loves it. They made my car smoother and noticeably increased performance.

Should have spent the extra money and gotten good spark plugs. I got a hit highway driving my 2000 Ford Ranger v6 3.0 4x4 within 2 or 3 days of installing it. the sound scared me to death. so hot that my wiper fluid reservoir melted so much that it had to be replaced.

Love the price! While the car only clocked 46,000 miles, the OEM dual platinum spark plugs were dropped. Incidentally, the car was 10 years old, so the original spark plugs were worn out from infrequent driving. An inexpensive solution immediately fixed the misfires due to the missing platinum disc at the end of the electrode increasing the gap. The car works like new.

I found out I have original platinum spark plugs on my car and this one is a step down. My engine shaking got a little worse, but I'm not sure if it's because I didn't change the coil on top of each spark plug or if I actually needed the platinum spark plugs. I carefully measured each cork. The car has become more powerful, but it still jerks at idle, the check engine lights do not light up.

added these to my 2001 Ford F-150, just bought with 1110.XXX miles. generally in good condition but because it has a lot of mileage (and you can never tell if the old owners did regular maintenance) I went ahead and serviced it, brake pads, coil pack and spark plugs regularly. They all came with the correct gap width, but take a gap gauge with you to be sure. Generally, this job will take a home mechanic with some experience a couple of hours rather than quick work. Some spark plug replacement…
