No haha

In fact, you are correct in a way. Spark plug from 2003 Focus 2.0 engine does fit MZR.

Reference # as follow

You better double check.

MZR feathre a taller engine head. Spark plug it use need a longer reach, 8mm longer than any of the 2.0/2.3 Focus Duratec using.

Hey V67, I was thinking if they are 8mm lower, I can go to the winch shop and ask for decreas 8mm to the spark plugs coupler, so they will reach, what do you think?

I don't get it. How can you decrease what is already 8mm short spark plug.

MZR spark plug into Duratec = too long and extent outside of the channel. Possible hitting piston

Duratec spark plug into MZR = too short and firing tip hide inside the channel. Not efficent firing.

Cheers Rod! So are all Duratec engine components interchangable with MZR components? Including the CNC cylinder head seen here http://www.f2usa.com/index.php?main_pag ... 1_2_184_92

Oz, It should fit, but remember that MZR uses VVT, It's a special pulley that move the time over high RPM to avoid the valves float, I don't know if that Duratec head fits with VVT, Cosworth sale MZR ported and big valve head, but much more expensive and it doesn't include racing stage 1 or 2 camshafts, valves, spring set and titanium retainers If it fits with VVT, it's a very good option, but remember only Duratec, cause the CNC is for Zetec and it's a different engine.

Please send an email to F2focus before buy one and ask them.

look at the wikipedia, it say in the 2.0L that MZR is the same engine as Ford Duratec DHE-420 http://en.wikipedia.org/wiki/Mazda_MZR_engine

Cheers!
