Worked great!
Excellent! My car was a little bit off and I swapped the plugs with these (much cheaper than the store) and they worked and still work great!

Smooth Startup and Improved MPG with NGK Laser Iridium
I recently installed the NGK SILZKR7B11 spark plugs, and I’m genuinely impressed. Installation was a breeze thanks to the pre‑gapped design and perfect OEM fit—no adjustments needed. From the very first start, my engine fires instantly and runs smoothly; acceleration feels crisper, and I’ve noticed about a 1–2 MPG boost on my daily commute. Highly recommend for anyone looking to sharpen throttle response and squeeze out a bit more fuel efficiency!

fired right up!
The price for these locally were astronomical! Glad I found these here. Fit perfectly, pre gapped which you don't wanna mess with anyway, and fired right up! 10/10 recommended!

Great product, great price!
I have always had great success with NGK spark plugs and all of my cars over the years, and this is no exception. My 2017 Hyundai was equipped with this exact plug from the factory, so when doing the 100,000 mi maintenance I replaced them with the same product since they are a proven entity and performed well over their lifespan. Buying these plugs from Amazon was considerably less expensive than going either through the dealer or retail stores, saving me at least $50 over what I would have spent elsewhere. Delivery was fast, and the product was exactly as expected. All the plugs were pregapped as advertised and did not require any adjustment (not that you would adjust iridium plugs... )

NGK plugs are what I always use after a bad experience with Champions in my Mopars.
The listing on Amazon contains the correct information, the spark plugs were indeed the correct ones for my car.

Good for another 100k miles
Worked out great for my 2015 Grand Cherokee 3.6L. Checked all gaps prior to installation and none needed adjustment.

Pleased with quality and performance and price
purchased for a 2017 Jeep Wrangler Sahara and no issues. I can see a difference in the Jeep performance. Replaced spark plugs was long overdue. Happy with quality of the product. pleased with price point.
