Pros:
1. Easy to install plug and play with the connectors, Hex and Combo wrench's to remove O2 sensors, and hex wrench to install plugs.
2. Very noticeable improvement with engine performance when used with my Rexxer map.
Cons:
1. May trigger O2 sensor faults until new settings are acquired. So you would need ability to reset the fault codes(Rexxer Evo User). I never tried the O2 Delete on OEM map so I cannot confirm this??? May need to let engine idle for 15min without touching throttle.
