NGK LKAR8AI9 Iridium Spark Plug for Bikes

It's really better than the stock spark plug . There is good change in acceleration and initial pick up also . A slight change of sound is also there . The engine get much smoother than earlier .Well change the plug at oil change time so u can really feel the difference in acceleration .It's also reduced the engine heat .Really good go for it.

Fits my 200ns as center spark plug.First let me bust some mythsPerformance will not increase drastically, it just improves combustion which leads to better throttle response and 2-3 kmpl mileage increment.Pros1.Can last up to 1 lakh km2.Made throttle response smooth and linear , lag free.3. Improves combustion thereby increasing a little amount of mileage.ConsIf you want to have changes in performance then you have to change spark cables to ngk spark cables and airfilter should be changed to performance oriented air filter like k&n and then the fuel supply should be tweaked accordingly to attain max out of your motorcycle.This is possible only with high compression bikes like Duke 390 and above 390cc superbikes.

I bought the plug a while ago, but did not go ahead and install it as my bike is already 2.5k kms past the previous service and roughly another 2.5k kms to go.I was very curious to test it and ended up swapping the stock Bosch plug with the NGK Iridium.The vehicle start felt normal. After a few minutes of idling, I started to roll and felt the difference in the first and second gear immediately. Its feels like the jerkiness while accelerating in the lower rpms is taken care of and now and it pulls much smoother down in the lower rev range. Need to test it out in different situations before updating this review.

Performance is good as stock champion plugs. Nothing much of a change in performance perspective.Longevity is much better than champion. I usually replace the stock plugs at 5k kms. As the centre electrode on stock plugs do wear out faster.My first set of NGKs lasted 7k+ and still is in pretty good condition.Definitely recommend to buy

Its around 15days that i'm using this in my ktm duke 125.. slide increased power in 3rd gear.. mileage increased around 2-3kms/liter.. but engine heats up a lot than before

Hope, It's work good. Price is a bit higher than MRP mentioned on the box. Overall very good stuff.Edit: After using I noticed-1: Engine running a bit smooth2: Solved unstable RPM3: Confidence It's last long

Received packing, with exterior Box fully crushed.This is a Refurbished Spark Plug and never buy this, you will end up spoiling your Bike Engine. The thread on the spark plug clearly shows the pre used of the product. The finish of the product should be Chrome and this is yellowish. So stay away and never buy this product.

Genuine product. After 4 years on conventional spark plug, switching to Iridium has not changed much but now I won’t be needing a spark plug change for a very long time as these last more than regular ones.
