The NGK BPR
5ES is the correct plug for Club cars, (FE290 & FE350)
The NGK BPR
4ES are for E-Z GOs,
Info per Carts Parts Plus:
Club Car http://www.cartpartsplus.com/spark-p...r-1992-07.html
E-Z GO http://www.cartpartsplus.com/spark-p...p-4-cycle.html
There's not much difference between the two, But If I remember correctly,
with NGK, the plug gets hotter with a smaller number!
And per my manual, the gap can be between .027" to .031"
Don't mind me Jimmie, your info will work! But, I'm just REALLY picky when it comes to
my cart!
