If I install a CAI, will I have to adjust the fuel injectors to use a richer mix? Cool air is denser than hot air (that's the point of the CAI, to get more oxygen to the engines), so less fuel will vaporize into the mix. More oxygen also means the engine will burn hotter; will I need to replace the spark plugs?

 

the answer is simple.......no...u dont have to touch anything. The cars o2 sensor will take care of that. Think about it......even if ur cars intake is stock......the temp in air differs say in December and July......so the computer will automaticly recognize what needs to be done.

 

its a pretty minor air/fuel change... the stock ECU can handle it.

 

ive heard of people running a few pounds of boost on the stock computer. so the tiny change of airflow and temperature with a CAI should be easily in the range of the ecu.
