NGK CR9EIA-9 Spark Plugs #6289 (4 Pack)

Super easy to install and works perfectly. Fixed the vibration in my car and improved fuel efficiency runs smoother and feels stronger. Excellent performance and quality.

Use these in my 2020 GSXR750 as it was time for a replacement set. They work great and are Iridium’s so it’s an added bonus to get the better quality. Fit exactly as expected and are the direct OEM replacements

The exact part I needed at a great price and delivered on time! These were ordered for my Gen2 Hayabusa GSX1300R motor that I have in my race car and I was getting it prepped for my next event. So getting this in a timely manner was nice!

My bike started running sluggish and was having a hard time to accelerate. I thought it was my injectors but my bike fires up fine. Decided to replace the spark plugs first and it did the trick. I use NGK spark plugs on my vehicles, motorhome and bike and you'll get the best quality of spark plugs. My old plugs lasted 15k miles and my bike runs and accelerates like its supposed to. Getting the spark plugs was a PITA on my gen4 zx10r but I took my time. The plugs came pre gap and that made the job easier. Overall, NGK is the best spark plugs for me and it won't disappoint!

My bike that I recently purchased was idling rough and had no power. To my surprise, it turned out the bike was neglected😨!! Those old spark plugs were on their last legs. It now doesn't bog out, and has so much power. These laser iridium plugs cost more, but are the OEM, and supposed to last longer than the nickel NGK CR9E, which can be used instead if on a tighter budget. The new spark plug on the image is on the top to compare to the old ones.

Worked for my kawasaki zx10r 2005

For 2016 Yamaha VMAX

They've only been in my bike for a day but I can feel it running smoother amd the data on my pcv, ignition module and auto tuner is showing small improvements across all ranges. Ngk is always a good brand to go with and these are no dissapointment
