small washer should be shipped with the kit

good, o-rings included were too small but the originals worked fine. also a washer should've been included because the screw on the lower charge pipe is too small for the corresponding hole in the new sensor. other than the the car has ran fine so far and everything works.

good build quality.

works with DDM charge pipes, harness and sensors look very nice. better than splicing the oem harness, if something goes wrong easy plug and play replacement
