Great Performance After Proper Gapping
Picked up these NGK Iridium IX LTR6IX-11 spark plugs for my 2009 Mazdaspeed3. Out of the box, they didn’t have the exact gap I needed, so I had to adjust them. Not a big deal, just something to be aware of.Once gapped properly, they performed great. Throttle response feels smoother and the engine runs clean. Definitely a solid upgrade over stock, especially for a turbocharged setup like the Speed3.If you're comfortable checking the gap yourself, these plugs are well worth it.

Perfect Replacement for MX-5
Replaced the 19 year-old spark plugs in my Mazda MX-5. Experienced an intermittent check engine light and occasional acceleration hiccup, after install installation of these and new coils no more check engine light and smooth acceleration, even when the engine is cold.

2018 F150 Coyote. Runs great.
Bought these to get iridium plugs back in my truck the factory changed to Platinum spec plugs for service intervals and they have a much shorter service life. Did them at 85K miles because I drive pretty hard and I found the factory recommended changing plugs at 65K if you tow a lot. I figured heavy right foot probably simulates some towing and the gap was out of spec already. Anyways, truck runs awesome, definitely idles and accelerates a smoother in traffic. Installed at the factory set .043” from NGK. Lots of people online freak out about it not being a .055” gap for the coyote. They run great. If anything they will burn to a .055” gap after a couple years of driving. But with these efficiently and performance results, I am very happy with these plugs in my 2018 F150 5.0 V8 Coyote
