Clean pair valve..mod

[Lord Popgun]

Ozi, the PAIR valve system is part of the emission control system.

From the Manual: The exhaust emission control system is composed of a pulse secondary air supply system, a 3-way ctalytic converter and PGM-FI system.

The pulse secondary air supply system introduces filtered air into the exhaust gases in the exhaust port. Fresh air is drawn into the exhaust port by the function of the PAIR control valve.

This charge of fresh air promotes burning of the unburned exhaust gases and changes a considerable amount of hydrocarbons and carbon monixide into relatively harmless carbon dioxide and water vapor.

The freed valve prevent reverse air flow through the system The PAIR control valve is operated by the solenoid valve. The solenoid valve is controlled by the PGM-FI unit and the fresh air passage is opened/closed according to the running condition.

OK, after all that, the PAIR valve mod will eliminate most/all popping that occurs on deceleration when using an aftermarket exhaust system.
