Their spark plugs are USELESS and ****. I hate the multi tip ones too. They tend to melt and you should stay away from them! Also their spark plug wires. Spark plug wires that are advertised as 10mm and 8.5 are referring to the size of the insulation, not the actual size of the core F.Y.I.

 

That is how spark plug wires are measured, by the size of the insulation. If your plugs are melting, you have the wrong heat range plugs for your engine,or the tuning is way off.

 

03 Dodge Neon melted plugs. Stock cross refrenced numbers.
01 Explorer Sport Stock cross refrenced numbers w/ intake and exhaust only
98 Dodge Intrepid " "
05 Hemi Ram " "
96 Camaro " "
The list continues

 

I repeat again, if your plugs are melting, you are using the wrong heat range, or type of plug for whatever combination of engine & mods you are using, regardless of brand.

 

The Murray's stopped selling them because they had so many problems with people melting them. EVEN STOCK ENGINES AS PER LISTED!
