Fit 2009 Acura TSX
I was skeptical about buying these thinking they were fake but they are the real deal. They had all the correct markings and the 4 digits on them.

No complaints so far and look to be genuine NGK
No complaints so far. I did inspect them before installing and they look to be genuine NGK spark plugs according to NGK's article "How to identify NGK SPARK PLUGS."The NGKs replaced fake Denso spark plugs from eBay that had worn center electrode tips after only 13k miles (my cheap fault). My worn spark plug gaps ranged from .065" to .073" when they're supposed to be around .044", which the NGKs are pre-gapped to. After installing the NGKs, instantly noticed the increase to normal engine performance.Ordered 2/11/25. Received and installed on my 2012 Acura TSX on 2/12/25.

Excellent Quality, Great price
While these aren't the cheapest, they aren't that much more than regular spark plugs (less than $10 difference). I'm happy to spend hat small amount to give me the peace of mind that these won't prematurely fail, causing me to have to reinstall them again.This was the first time I had changed out spark plugs. Installing them was smooth. I double checked all the gaps and they are to spec so i didn't have to do any adjustments. They pretty much went as you'd expect.I bought 3 boxes (to change out 2 cars). This was 2 months ago and they fixed the rough idle/misfire in one of the cars. The other car seems to be getting better mpg (nothing significant, just a noticeable small increase).Excellent product!

Acura TSX
Spark plugs work like a charm. I put these in an 2011 acura TSX. Same ad dealer plugs. I high recommended.

4pk only
My only complaint is, it's a 4pk. There no other quantities available. I only needed 6 but have to purchase 8😑.

Enhanced Engine Performance with NGK Laser Iridium Spark Plugs
Upgrading to the NGK ILZKR7B-11S Laser Iridium Spark Plugs was long overdue for my CRV, which has clocked 180,000 miles. I suspect the previous owner neglected spark plug maintenance, as the plugs were the same brand and likely hadn't been changed. The difference after installing these plugs was remarkable. Not only were they easy to replace, but they also significantly improved engine performance. With features like the laser-welded iridium center electrode tip and platinum disc welded to the ground electrode, these plugs offer enhanced durability and better spark, leading to smoother starts and improved acceleration. Given my vehicle's high mileage, these spark plugs were a much-needed upgrade, ensuring optimal engine performance and efficiency.
