Autolite 3924 Copper Resistor Automotive Replacement Spark Plugs (4 Pack)

Works great on my 2006 Scion XB. No problems.

Good replacement plug for Briggs and Stratton 2-cylinder gas mower engines.

My lawn mower was getting hard to start. I thought it might be the fuel or carb. But turned out the spark plug was bad. Put the new plug in and my mower now starts on the first or second pull and runs like new. Easy and inexpensive fix. I would buy again when needed.

Works great on 500 hp sbc

It powered up my old mower that suddenly stopped half way through yard. The quality of the plug was good but the carton was crumpled and both ends open and squished flat.

Always used auto light spark plugs. This is the same quality good product?

These engine plug works like magic I will buy more for future use

Replaced and engine fired right up, excellent price half the cost of automotive stores. These plugs are gritty and get the job done for all small block fords.
