🔌 Bosch Automotive (9605) OE Double Iridium Fine Wire Spark Plug - Single Review

You are fine. Comes with a big twist. It is EXTREMELY DIFFICULT to close the gap. If you don't have a professional gap detection tool, you're done. No difference in performance.

Used 6 of these for my car, got 6 of these but one broke accidentally, Amazon sent this to me quickly so I can tune my car with a great spark plug. They are better than most spark plugs available at my local auto parts store.

It took about 2.5 hours to replace all 8 spark plugs on my Ford F-250. The local dealer asked $350 for it. Don't let the online stuff put you off about how difficult it is to do it yourself. If you have moderate mechanical skills and the right tools, the job won't be too difficult.

They work and my daughter is happy, I saved her money with a discount and the job was a little easier than expected. Rear of the transverse motor mount, so a few grazed wrists and knuckles or two and we were in business. You breathed new life into an old car.

I use these in my Ford Ranger V6 3.0. They give a noticeable increase in strength. The engine sounds solid and has more throttle response when shifting gears or driving at high speeds. They do their thing. Gasoline mileage is fine and I use ethanol free gasoline as it gives me more mpg. It's a converted '95 and it's purring down the freeway. I am fortunate to have a great mechanic who works for me and who I can rely on if anything goes wrong day or night.
