Just installed V&H BSS, K&N a/c, and PCIII. Absolutly love the upgrade. Performance and sound is awsome. My question is w/ the O2 sensor. The PCIII eliminates them. So do I just cut the wires off the OEM sensors and leave them in or is there a plug made to replace the OEM sensor. I figured less restriction in the pipes is better.

 

The PCIII come with little "Plugs" that you have to put in the ends of the O2 wires. Without them, your ECU will freak.

If you got pipts with O2 bungs, you'll need to put plugs in the holes

 

Or just put the O2 sensors in the bungs and leave the wiring in place, in case you ever need to use the sensors (perhaps when they start checking emissions). Doesn't hurt to leave them in place (with the O2 eliminators plugged into the connectors), and it looks more legitimate if the authorities snoop around.

Yeah, I got the pipes w/ the O2 bungs. Do I use the sensors out off the stock pipes and cut the wires off them or do they make some type of less restrictive plug.

 

The stock O2 sensors just unplug from the wiring harness and you plug in the O2 eliminators, no need to cut any wires and if you leave them in the pipes they are not a restriction, or you could take them out and screw in some plugs.

 

I would not cut them you may need them someday.
