MG MG Y Type - Spark Plugs and Oil Filter

I've serached the archives and found differing numbers for the proper modern spark plug to use in my '53 YB. I found reference to both N9Y and N5C plugs. Which is correct?

Also, is a standard TD oil filter cartridge the correct replacement for the original canister filter?

Thanks all!
Steve Simmons

Steve,

The original YB Workshop manual says Champion L. 10.S 14mm (Champion NAB on later models) so with a '53 I would go for Champion NAB (or equivalent) if I were you.

Gap should be 0.020 - 0.022".

Hi Steve

My '52YB0998 uses NGK-IRIDIUM-Spark-Plug/BPR6HIX for many years. But, this IRIDIUM Plug can't get good performance by the adjustment of the thick fuel. �@Usually, BP5HS is used for XPAG.

(The standard of PLug may be a Japanese domestic standard.)

Steve - If you have the oil filter that is an integral part of the oil pump (horizontal filter housing) then the standard (late) TD/TF/MGA/early MGB oil filter cartrige will work. A few different part numbers are Hastings P172, AC AC32A, Fram CH814PL plus numerous others. Cheers - Dave

Thanks all!

Paul, I asked my local parts house guy for a set of Champion NAB plugs and he looked at me like I was from another planet. Do you have a source for them?
Steve Simmons

Steve,
The NAB code is probably a very old code. Ask your stockist to cross-reference the NGK BP5HS that Masaaki suggests to a Champion code, or better still buy the NGK!
The N9Y (same as your MGB?) you found is probably too cold for a single carburettored Y.

Here's some info on heat ranges

The current equivalent Champion Spark Plugs are:

L82 or L82C - Early XPAG engines with short reach plugs.

N5 or N5C - Later XPAG engines (SC2 etc)

Both of the above are still available.

Regards.

The size of NGK-IRIDIUM-Spark-Plug/BPR6HIX is the same as NGK-BP5HS.
The electrode part of NGK-B5HS is short in comparison with BP5HS.
The length of the screw is the same.
The dimension of the outer electrode part.
B5HS is about 3.5mm. BP5HS is about 6mm. T
he length of the screw except for the washer is about 13.0mm.
