MG MGF Technical - 52 mm throttle body.

I wold like comments from anyone who's fitted a 52mm throttle body.
I am interested to know if the improvement is worth the expense.

I've had one a couple of years and the throttle does seem more responsive. This usually a good thing, but if your cable is sticky like mine before I replaced it, it make cause excessive revving when pulling away.

Really depends if youl ike the boy-racer effect; personally I don't.

I found the car to be more flexible following fitting the 52mm throttle body to my 1.8i. I did at the same time though fit a later twin inlet air cleaner box with an ITG panel filter.

I did it a few years ago. It does seem to make a difference when coupled with a 57i kit. After I did it the idle speed was wrong as the calibration on the new throttle position sensor (TPS) will need to be set (using Testbook). You can sort this by swapping the old TPS from your current throttle. This worked for me and a couple of others who tried it. Should be stuff on the archive

Didn't have a problem with idle speed, I believe if you check the archive you do something like depress the accelerator 4 times with the ignition on but the engine not running to reset the TPS. ( May be a different ignition switch setting it is a long time ago!)

Get one!
You won't regret it, and fitted mine in my lonch hour at work...!
