CAP Can Auto Performance O2 Spacers 90 Degree - Set of 2 (Pair)

Just what I needed

As with all CAP products, these O2 spacers are well-made, very sturdy, and just what I needed to keep the CEL away when running my test pipes.

very nice

Easy install.

They definitely help. If I run it hard and then immediately drive mellow the sensors still throw a rich/lean code. Consistent mellow driving is code free.
