4644-4PK 4644 BKR7E Standard Spark Plug, Pack of 4

Came packaged well, exactly as described and works well.

as always NGK proves to be an amazing company. i wasn't sure what plugs i should run for my new engine build at the power/boost level i plan to be at. a quick email to the folks at NGK and they replied within an hour with recommendations, explanations, part #'s, etc.. i've never had issues with their plugs and their customer service is outstanding. top quality parts from a top quality company.

Best prices for these NGK spark plugs. If you have a turbocharged Honda, these are the ones you will need. I usually gap them to .018" but may differ depending on motor and setup.

These work a lot better than Platinum or Iridium, but they last 1/4th as long. Copper plugs give you more complete combustion, and less chance for knock, given you keep the gap in spec throughout the plug's lifetime.

Perfect fit and function, will continue to buy these

AS ordered and works great

Revived the motor on my 1.4 vehicle.

Currently in a gt28 audi 1.8t with 22lbs of boost. They last about 5-7k miles before needing cleaning and about 10k before being bad.

seems to be genuine ngk product. work good in my 1.8 turbo audi a4. would buy again

These worked great on my chip tuned VW 1.8t. Resolved a possible detonation issue caused by my old worn plugs. The copper core seems to have done the trick by effectively transfering heat away from the combustion chamber. Product arrives with each plug individually boxed. Spark plugs were slightly inconsistant when it came to gapping. I also bought a small spark plug gap tool for less than $10 and it worked great to gap the uniformly.

nice item

Très bonne performance

OEM replacement for 2012 Chevy cruze. Showed up fast, preform as expected. These last about 50000klms before I change them but I'm sure they would be fine for up to 100000.
