NGK (6988) BKR7EIX-11 Iridium IX Spark Plug, Pack of 2

So, when you or your mechanic feel you need new spark plugs what are you going to buy? Cheap copper core plugs designed in the 1910's or the newest, most up to date plug you can get your hands on? I researched the problem. I looked at several brands and several styles from platinum, multi-tip, split-tip and so forth. I've used and thought kindly of the 4-prong plugs. Why did I switch? No particular reason other than I wanted the Iridium core. The spark plugs I removed were NGK. Not surprising as it was a Japanese vehicle. Ergo, back went the best NGK spark plugs I could find. These were well built, installed easily, and made a gratifying difference. Use anti-seize on the threads and spark plug grease on the tip. I expect another 50,000 miles from these plugs. Oh, I also change the spark plug wires when I change plugs. In my experience you can damage a wire just pulling it, or find one abraded from rubbing on a motor part. You are there anyway.

NGK plugs have always had a great reputation. These iridium plugs are even better. I installed on a Polaris RZR 800. I see quicker starts, better idle, and maybe even an increase in horse power. I do recommend careful action to set plug gap. The iridium positive core is very small and might be damaged by efforts to set gap. I used a spark plug gap tool that allows careful bending of negative pole.

I needed a new set to clear up a misfire on my 2012 mk 6 gti and these did the job. They were gapped how I needed so I just had to swap them out. 15 minutes and done.

What is there to say? They're NGK Iridium plugs. Why are you even reading this? You already know how well these plugs work and how you can depend on them. They're all I put in any of my cars.

NGK is a great company that produces excellent spark plugs. Know your engine's power/heat requirements 7 doesn't mean more power, it means less area of spark generation is exposed to combustion gases, thus its referred to as "colder" Right now I am actually using NGK heatrange 6 because I don't need 7's at this exact moment.

I have always veen pleased with these plugs. I use them in my tubocharged 1991 nissan sentra with a MSD & they have always held the power well. I use the same plugs in a 2004 subaru impreza with sti internals and tuning and no complaints

Can definitely feel the difference after I got them installed worth it

My RZR didn't have any real issues, or so I thought. When I installed these as preventative measure since I had the rear end apart, I noticed the idle was a little smoother and I can get to my top speed a little quicker. My old plug boots had mud in them, that was more than likely the culprit, but I'll give these plugs the credit!
