NGK R4118S-9 is the stocl plug but they are hard to find. Here is the answer I got from NGK for a replacement - - Hello,
The iridium BR9EIX stock# 3981 can be used in its place. The iridium plug has a slightly finer center electrode diameter and should give improved performance.

There is no spark plug cap located on the 1993 Chevy Blazer. The spark plug gap for this vehicle varies depending on the type of spark plug that is used. The OEM spark plug gap for this year is 0.040.
The correct spark plug socket with a really long extension
NGK type plugs are DPR7EA-9.

Anyplace that sells spark plugs will have an application chart which will tell you what plugs will work in your Kawasaki.
I am not 100% certain, and I am no mechanic; However, I have always used 0.028" on my 1996 Suzuki King Quads with no problems.
The correct spark plug gap does not depend on which plug you use, it is dependant on what engine it is installed in. The same plug can be used in many different engines, and each engine might have a different gap specification. Instead, you need to ask something like: What is the correct spark plug gap for a 1993 Chevy 350 engine? (or whatever engine you have).
Our concrete saw uses that kind of spark plug
The best spark plug for racing in a Suzuki Raider 150 (FU-SC or FU-SCD 150) is the BOSCH Iridium spark plug. This plug does not miss a spark at low (3,000 RPM) or high (11,000 to 12,500 RPM) engine revolutions. It is best used at full throttle races. The BOSCH Iridium is best used in high-intensity drag races (quarter-mile or more), giving a consistent high power fuel-burning capacity that will not scar the Suzuki Raider 150's piston. Extreme modifications to the Raider 150 engine, coupled with high-intensity spark plugs, may scar or even tear holes onto the piston's top end. For Circuit Racing, where there is the tendency to use low gears on slowing down, as well as rapid up-shifting to gain speed, the best spark plug to use in the Suzuki Raider 150 or R150 is the NGK G-Power plug. It provides consistent fuel-burning spark on rapid slowdowns (using the engine as a brake, or engine-braking).
A sp-34 spark plug to a Champion plug is a small engine spark plug. They can be used for lawnmowers and weed eaters among other things.
