NGK - DPR8EIX-9

I added these with a K&N air filter on my 2003 Bonneville and I have to say they have really help on the low end power and easier starting.

Great performance from new plugs

I added a K&N filter to my Bonneville but it was the addition of the new Iridium plugs that made the noticeable improvement in acceleration and starting. I plan on using them in other vehicles as well.

NGK - DPR8EIX-9 IRIDIUM SPARK PLUG

This plug put new life into my 2008 Honda XR 650L motorcycle. I did mod my bike including exhaust system, high performance air filter, and had it tuned and re-jetted. The stock spark plug did not make the bike run properly after I completed the mods to my bike.

NGK DPR8EIX-9 - Iridium Spark Plug

They give better performance, better gas mileage and we will have to wait and see about the life of them will be, but thank you all for helping with service and the fast shipping. Motorcycle Superstore is #1.

Astounding Difference!

These plugs should be OEM -- they are exponentially better than the standard factory plugs that require replacement at 4-6 K miles. Very noticeable added power and spec's say good for 60,000 miles or more. At $9 bucks, a higher price that give much lower cost!

NGK does it again!

Although these plugs do indeed take additional power to spark, they made a marked difference in the performance of my 1984 Honda Goldwing. Noticed better pick up and overall power. I changed the air filter as well but it was only a year old and in great shape. I will be using these plugs from now on at least till NGK comes out with a better product!

These plugs woke up my V-Max

I noticed an immediate difference. on cold start. My mileage went up by about 2mpg. And my throttle response is more crisp. They are worth every penny.

Iridium plugs

Not much change from old standard plugs. May start easier when cold. No change in gas mileage. Only time will tell if they are worth $10 each.

irideum plugs

Put these on my triumph sprint. Take off gas tank, take off air cleaner, remove coils, 14 mm socket to remove plugs. Reverse process. Maintenence is not the best or easiest, plugs made a difference in starting.

Not good for single cyl XR600

Gave it poor rating only based on bad performance on my bike. May be a good plug for other engines. My bike, an XR 600R year 1993. This single 600cc cyl engine puts too much strain in the thin iridium electrode, and ends up destroying it with time. It gets dirty very quick and to kick start the bike is a bit of a nightmare. Stick to your standard plug on this bikes.
