NGK (6481) ILFR6B Laser Iridium Spark Plug, Pack of 1

OE replacement for my 2008 subaru outback. I did have to regap them since amazon didn't have them in the factory spec gap.These are the longer life laser iridium plugs, which I like to use in cars where getting at the spark plugs is painful. For cars with easy to replace spark plugs, not sure the cost is worth it...

I installed this plug in my 2003 Subaru Outback H6 at 102,000 miles. I purchased the car at 89,000 with very few records, but I'm pretty sure the original platinum plugs were unchanged judging from the wear on the electrode and the cleanliness of the red plug boots when they came out (I got dirt and grease on them during install and had to wipe them several times). I immediately noticed significant power increases (compared to the overused platinums) and am enjoying driving my Subaru very much now. One thing to note; these are not the correct plugs for a 2003 H6. They are gapped for the 2005 and up at 0.030 inch. My car calls for 0.039 to 0.043 and NGK recommends a maximum gap correction of 0.008 because of the ground electrode becoming misaligned. The 0.030 gap however was somewhat pinched and when I gapped them out to 0.038 +/- 0.001 the ground actually lined up better and directly over the center of the tip. So far, I am very pleased with my selection and would recommend them to any Subaru H6 owner.

Gap was preset to .03" as needed. The plugs are well made. My only complaint is that these were shipped in the same package as some other tools, which moved around during shipping, causing a couple of the plugs to come out of the little boxes. There wasn't any visual damage but the electrode tips are very small and fragile on these so it was concerning. Be aware that if you buy these, try not to combine with other orders. Car runs great ('04 Forester XT).

Bought these for my 04 Sti and they are really nice. Price is right

A Sparkplug is a sparkplug, but I am offended about Amazon's misleading advertising. If I had known that the free postage offer would not be honoured, I would have examined the other offers much more carefully, and probably made a different decision!PeterB

Bought these for my 2011 Volvo S40 T5. It runs great and I have no problems. Seems to run a little bit smoother and has slightly more power after changing from the original plugs.

It's a spark plug that provides spark when summoned to do so at a cheaper price than advance. I have never had any issues with them. I replace at 5 years regardless. Used in a boat.

My goal was to get the same plugs used in my lr2 and these spark plugs are the same ones used in my lr2. Easy to install, took about an hour.As a tip make sure to buy anti seize lubricant and apply to threads even though the metal on these "claim" to not seize.
