so my jdm b16a didnt come with the ckf. im trying to get it emissions legal i know that i need the american oil pump for it to mount to. i called the parts store and they said they have the sensor but in two sizes 18mm and 20mm on has the bolt hole vertical and the other has the bolt hole parallel to the sensor. what is the difference between the two (besides the bolt hole) and which one do i use.

 

bump for some help

 

bump again

Maybe it will work for you without having to buy anything else.

 

i want to stay away from the ecu tricks they tend to cause other problems

 

These pics might help, they might not. This is from when I added the CKF to my B16.
