NGK 4344 LTR5IX-11 Spark Plug (Iridium IX) (pack of 4)

ممتازة

I'm running a 2002 Ford Focus 2.0L with 304, 000 miles. Great plug so far. My first experience with iridium plugs. I was a little hesitant to go off the reservation and switch from Motorcraft to NGK and iridium NGK at that! The lady at autozone freaked me out a little bit saying how you should just stay with OEM Motorcraft blah blah blah blah, but after reading Amazon reviews as well as searching YouTube and the rest of the internet, I took the plunge. I already have logged almost 2,000 miles, & I have seen a huge difference in gas mileage and smoothness. A little bit more power too. I had some confusion on whether I should gap them to a different setting other than the factory. Specs I saw for my vehicle were 0.50, they come pregapped at 0.44. I went with the specs. Just make sure you have the correct gapping tool to adjust it. From what I understand it doesn't take much to ruin these plugs . It's been running fine with no misfires or check engine light, so, so far so good.

Great price, fast delivery!

parfait comme je voulais

I really know very little about cars, but was looking to improve the performance of my 2009 2.5L 4cyl Mazda6. (It's a great car, but I have always felt it could use a little more horsepower.) After reviewing all of the helpful reviews on Amazon, my local mechanic dropped them in, since I would have no clue what to do, and voila! Instant improved engine performance! I did purchase new tires at the same time of installation, so certainly the combination of the two would result in improved overall performance, but you can really tell the engine itself is working better. I have not noticed an improvement in mpg yet, but mostly because I'm doing a lot more accelerating.

Exactly what it said it was
