Added a clamp to the back of the intake to hold in that MAP sensor. Didn't come with a clamp, also only had a blind hole that needed drilling as not all applications need it.
Test printed in cheap material to make sure no oddities. Was something on the bottom part where it was too thin. Test print also good to see size and check fitment. The bottom bit would cost over Ā£25 to print in high temperature material. Test printing around Ā£5.
Happy with the top bit, no further changes to be made. It's come out really well. Happy with that.
See int he vlalled there is a black circle, there is another further along. Under these are little microphones, called Knock sensors, they detect detonation of the engine and retart the timing if need be. These are the originals, 25 years old, 200k miles old. They can become sensative over time, also there was an altertation after 2000, so in 2001 and 2002 were alterations to avoid fals knock. Now I do see diring logging I do get some knock detected, but I do/did have the exhaust touching the body at time. Anyway I'll fit new ones., its about time.
They just screw into a thread on the block. easy to swap out. Providing nothing breaks on the wiring, or the plastic.
Atleast they are not made in China. These are Mexican.
