Stens 130-143 NGK Spark Plug, NGK 4929/DPR8EA-9, ea, 1

Fits, good product, easy installation

Great spark plugs, the exact type my motorcycle required. Very good quality plugs, gap already set appropriately. They all come cylindrical cardboard tube over electrode to protect plugs while in the box. So you have no worries of your box being dropped and cracking your porcelain around the electrode. Very clean, crisp threads and installed in motorcycle heads with ease. INSERT tip: using a 3/8" rubber hose approximately 6-8" long, slide it over the top end of plug and use to insert plug into place. If you begin to cross thread during insertion the rubber hose will slip around plug. Whereas, with a ratchet one might be apt to keep tightening at this point, thus ruining the female threads in your cylinder head. Update- July 2015, its been a few years since I have replaced these plugs. Motorcycle still running strong. Great plugs. After initial replacement, my motorcycle had a felt increase and sense in horsepower...not dramatically increased of course but I could tell that these plugs were indeed causing my motorcycle to run with a little pep in her step.

E Z to install Excellent product for my quad Turns on right away

The product worked great. I gaped them and they fired right up. I just felt they were to expensive. However I have been wrong before.

Excelente

NGK makes a great plug but, this spark plug WILL NOT work in the 2007 CAN-AM Outlander 650. The shank and threads are the right size and, can be screwed into the head, but, this spark plug uses a 18mm socket that WILL NOT fit into the head. This spark plug fits fine but, you cant tighten it. The original spark plug uses a 5/8" or 16mm socket or the spark plug tool in the tool kit. I use NGK in my Husqvarna chain saws and just about everything else. I can use these plugs elsewhere so it was a good buy. Great plugs.

Muy buena calidad

Fit my motorbike well. Would recommend.

Good quality item.
