FB15 Spark Plugs

[Deepal Priyanga]

Hi,

I have a FB15 1500cc 2000 YOM super saloon. Spark plugs model currently existing in my car is NGK BKR5E. One mechanic recently told me that spark plugs in my car are not the exact model intended for my car. He said that it should be BKR5E-11. Anyone knows the difference between these two models and should i get replaced the existing plugs with BKR5E-11 as mechanic told?

BKR5E is standard gap which should be 0.7mm whereas BKR5E-11 is 1.1 mm gap. It is always better to use the recommended one but other properties being equal with BKR5E-11, the gap in a BKR5E can be adjusted to 1.1mm.

Since you're on the subject of plugs, why not get a new set?

Your car will perform better.
