PC3 and PAIR Valve Mod


kst

Question

As I understand it, the PAIR valve introduces fresh air into the exhaust for emissions purposes.  The air goes in before the O2 sensor hence the popular PAIR valve mod.

 

If an O2 eliminator is installed (e.g. with a PC3), wouldn't that make the PAIR valve mod obsolete?

While it does make it obsolete, you can remove all the PAIR plumbing and install block off plates on the engine to make things a tad tidier.
