Converting Spark Plug Codes

[Birnie]

Hi,

I have the sparkies code IFR6T11 for a mates car which seems to be the universally recommended plug for this car.

We just don't see the point forking out the $$ for Iridiums.

Nearly $100 for 4 plugs.

How do i convert back to coppers for these?

NGK let you do the up conversion but not the down (dodgey kents)

Thanks guys

I = Iridiums.

F = M14 x 1.25mm thred, 19mm reach

R = Resistor.

6 = Heat Range.

T = Unsure of the excact feature but it is a Design Feature of the Plug.

11 = Gap.

Try using a BCPR6ES-11 or a BKR6ES-11 they match all the specs of the iridiums but as coppers. the only differance between the two is the distance from the gasket to the top terminal is 2.5mm shorter on the BK plug.
