Spark PLug for the right job, July 21, 2009

Well this is what my Honda powered Craftsman lawn mower requires and it does the job just fine. NGK is what came out and NGK is what went in. The old plug lasted me over two years and to be honest it didn't show fouling or too much wear on the electrode.

Awesome OEM Spark Plug, June 3, 2013

P. Miller (Virginia) - See all my reviews

This review is from: NGK BKR5E Spark Plug, Pack of 1 (Automotive)

I picked up one of these V-Power Spark Plugs from NGK because they are the most reliable on the market. I used to ride motorcycles and if you used a Champion brand, you were going to have trouble before the summer was over.

This spark plug fits my lawnmower, I did a valve adjustment and it runs like new. The application is a Briggs & Stratton InTek (18.5 HP) in a Craftsman / Husqvarna lawn tractor. It had the original RC12YC plug and I replaced it just because it was 6-7 years old.

Installation Tip: Use a little anti-seize on the threads and some dielectric grease on the ceramic end to keep the boot from getting baked on. This is stuff I learned working in the automotive industry.
