can someone give me instructions on how to remove the coolant hoses from the throttle body and therefore not heat up the air intake Ive heard it mentioned on here but not seen it discussed in detail. Thanks in advance.

I tucked them above the icv bracket and then bolted the icv back on to hold them.

Not ideal but it works! :snigger:

this only really benefits the 318iS engine which has a massive heater plate. The one on an M20 is much smaller and i don't think there will be any real benefit unlike on the M42

No harm in doing it though, it all helps :)

Having said that, the heater can't change the temp of the air by a huge amount as the air temp sensor is in the AFM and so the ECU wouldn't know about your mod, from which we can deduce that it dun't make that much difference to anything.
