Hey guys. I've heard that installing an intake system on your car can potentially ruin your catalytic converter. I just got a stillen high flow system for a steal. does anyone know anything about that? or has anyone been running the stillen high flow with the z tube for a while?

 

False.

 

Never heard that before. All your doing is increasing air flow.

 

old wives tales!!

 

thanks guys!

 

Total B.S., someones blowing smoke up your porthole! Most of us get an intake/z-tube in the very beginning just because they change the sound of our VQ motors. My OE cats are 8 years old and they still work perfectly when I need to pass smog. Two things kill OE cats, using leaded gas or having a blown engine....very little else other than time itself....Gary

 

That would be false.

Technically catalytic converters should last the life of the car. There are no moving parts in the cat, only a chemical reaction that converts Hydrocarbons, Carbon Monoxide and Oxides of Nitrous into Carbon Dioxide and Water.

Cats can however be contaminated by excess fuel (rich condition), an excessively lean condition (not enough fuel in the combustion chamber), burning oil (bad PCV system or excessive blowby from the piston rings), coolant (blown head gasket) or if you're lowered and you bang your cats on speed bumps or other imperfections in the road.

 

Someone probably had something unrelated happen to their cats after installing an intake then a mechanic who was too lazy to diagnose said it was related and thats what probably happened. I agree with everyone else, I have never heard of an intake messing up the cats on any of the car platforms I have been involved with.

 

This does sound like some service writer at the stealership making an excuse why converters fail....gotta be the CAI!
