Spark plug NGK or OEM FORD

I've had multiple Chevy engines that gave random misfire codes with autolite plugs- then ran fine on ngk.

If you want relatively inexpensive and decent look up whatever NGK plug is correct for your car.

I find the car runs way better on the Rutheniums, and I find that the plug gap doesn’t open itself up over time like it was with 6510s.

I went NGK and noticed a small bump in throttle response, changed mine at 100k Km (60k miles) and they were honestly good to throw back in too, so not like the plugs were burnt or fried!

I’ve been running NGK Ruthenium plugs on my stage 1 GTI for 20k miles. No issues.

NGK. I'm a believer after using them.

My 2000 Ford Ranger with a 4-cylinder and manual is just about the simplest vehicle that could exist. SOHC engine, so not much that can go wrong in it. It's very satisfying to work on because you don't experience the shitty feeling of knowing you spent way longer on something than it should have taken.

Went and bought the NKG plugs and the problems went away.

2013 3.5 hitting 170k miles within a few days. Second owner so not sure how it was maintained during it\u2019s life but I\u2019ve done 10k miles so far, needed a waterpump and sparkplugs but it\u2019s pretty normal wear and tear

after putting the new ones i changed all the spark plugs too, to fit them properly with new wires. but the car runned roughly, so bad..and when mechanic unscrew the new spark plugs to see, they were carbonized black, with just a ride around.
