if i change from a k&n air filter to lets say an hks one will i need to remap reason being theres not enough room because of the front mount pipe work. the car has already been mapped and is running 1.55 bar on a tdo5 18g and 550 power engineering injectors and a few other bits and bobs..cheers for any help..

 

if it's just the filter itself ie, the pipework is not changed, it should be okay. If you change the pipework then yip rescale would be a good idea.

 

much appreciated prana
