Looking for some different ideas. I've got 3 but I'd like to see what other people are doing and maybe I'll like it better.
Thanks Mike

 

I just installed my pro-M and 50's, I drilled a hole in the rubber boot behind the mass air and put it there, I'm sure there is better place for it but that's where I put it.

 

In my C&L boot...

 

On the bottom of the boot about halfway between the MAFS and the throttle body.

 

I figured most would put it there. The only thing is my water nozzles are in my boot and although they spray at the TB water mist could get on the sensor, or maybe I'm being paranoid. I thought about putting it in the end of the filter , but that might look cheap plus the wires may not reach.

Thanks Mike
