no1kicker Posted June 15, 2005 Report Posted June 15, 2005 Is this ok to use with the tube plugged? (for emissions only ) Quote
Canada Posted June 15, 2005 Report Posted June 15, 2005 All the tube does is allow some extra air to enter the cat to help it work better. Quote
DaveFromColorado Posted June 15, 2005 Report Posted June 15, 2005 yeah, the air tube is a "preheater" and on the air pump cars, it stops pumping the air into it once the engine comes up to normal operating tempature - there's a lot of cars out there running with that tube plugged with no adverse effects. --Dave.
