NGK ITR6F13 Laser Iridium Spark Plug

Perfect fit for Mazda 6, 2004, 2.3L Engine, Sedan.ITR6F-13, Lazer Iridium Spark Plugs, Pre-Gaped (no need to touch the gap), Perfect fit and size as the OEM spark plugs.Amazing Quality, Honestly THE BEST SPARK PLUGS YOU CAN FIND FOR YOUR CAR.LAST FOR EVER xDI also Bought NGK Spark Plug Wires Cuz mine was dead.The whole process took me around 15 mins. Very easy to install, Works like charm.

I had my original spark plugs for over 75k miles and they were due for a change. I did my research online and found that most of the Mazda 3 forum sites recommended this plug for 2005 Mazda 3 or earlier. Everyone I read said the gaps were correct from the factory (always check anyway). The install was easy and I have been running them for a while with no issues. The car seems to have a little more pep then it did before. I would recommend these plugs.

Although Amazon shows that this product doesn't fit my vehicle, my vehicle workshop manual recommends this exact spark plug. NGK spark plugs work very well :)

These spark plugs are of excellent quality. I did a lot of research, and these are highly recommended. For only 20% of what the local car shops charge, I was able to change my own plugs very easily. The best feature is that these are pre-gapped, meaning that you don't need to adjust them in any way. Just buy the correct part number according to your car manual specifications. Be sure to compare the "gap" listed in your car manual to the "gap" listed for the spark plugs that you intend to buy. It was so easy that even I could do it.

Happy with the performance and price. Product matches the quality of the seller - Amazon. There are cheaper products, but in the states were temperatures are around and above 100 F - does the job forever.

I wanted to replace my cars spark plugs and was not sure of the brand to go with...after some research I was directed to Amazon.com for great service with a lot of plugs to choose from.. depending on price and quality...I went with the NGK ITR6F-13. WOW! what a difference new plugs make..... I did not have to re-gap them, (i however checked them to make sure) out of the box into my car,& in 20 minutes I'm back on the road:) kudos NGK for making life simple and smooth idiling.

fake plugs dont buy

I installed these in my 2005 Mazda 3 with the 2.3L engine. On this car the spark plugs are run by coil packs that sit directly on the spark plugs, so there is nothing else to replace when getting new spark plugs. It took me about 25 minutes to replace all four plugs. They sit right on top of the engine and are easily accessible. The only specialized tool I'd recommend is a torque wrench that can reach 17 lb*ft of torque. Some dealerships will charge over $200 to replace your spark plugs, so this is an excellent candidate for a task that is fast, easy, and requires little (if any) clean-up that you can try yourself and save some serious cash.
