good plugs
I have a 1952 Ford F-2 pickup 3/4 ton that has the V-8 flat head engine and it floods easily and as all engines of this era did it burns some oil ruins plugs so I tried NGK and so far they are working out,time will tell.I also have a 1954 Ford Customline 2 door sedan with a 239 overhead valve V-8 and will be ordering a set of NGK plugs for it also.I like to carry spares because these older engines with carburators and manuel chokes all have a mind of there own and no two start with the same set of rules.Some you need to pump the gas several times some not so much and some not at all and also it depends if the engine is cold warm or hot or if it is raining they respond differently so again plugs do not usually last very long.

No Julian, this NGK Standard Spark Plug (CR5HSB) (Part # 6535) does not fit your CAT RP5500. The exact spark plug for your application is currently unavailable online. I would suggest that you visit the nearest Advance Auto Parts store to check the availability of this part.
Is this a good plug for moped

Hi Donnie, I'm glad to help you! We can only look up by the vehicle. Since you didn't mention the specific vehicle, it's hard to tell for sure. To give you the correct information I would need the year, make, model and engine size of the vehicle.
