Hi

I have just bought a saito 56 which came supplied with a saito glowplug.

Is it worth replcing this for an OS.F?

Thanks....................Trev

I have some of them, so far I haven't been able to tell any difference between the Saito plug and the OS F.

Bill.

Not at 8 bucks a throw

The Saito plug has a list of $6.99

The OS "F" is $7.49 list price

The H9 Super plug for 4 strokes is $5.99

Not a whole lot of difference in price

I have been running the SUPER plug for a while and cannot tell the difference from an OS F, and it only sets you back about $5.00.

SAITO Super Plug is slightly hotter than OS-F. I have been using both of them, the SAITO for 15 to 20% Nitro fuel and OS-F for YS Engines on 20 to 25% Nitro fuel.

Thanks for the info guys,much apreciated.

Trev...............

Central Hobbies has OS F plugs for about $5 or so each. I got quite a few not too long ago.

Well, they deleted at least two posts on this page

I have been running the plug that came with my .65 since new with no problems. It has about 10 gallons thruogh it now.
