I rencently installed a full megan from header to axle and no light but yesterday I changed my ssr for the stock intake and today the light showed up. Any ideas?

 

reseat intake and retighten

 

intake isnt gonna cause your CEL.

the cat delete is your problem. sometimes takes a while for the cat-delete CEL to coem up, but its usually inevitable. get the code scanned, its prolby a code related to cat efficianty or secondary o2 sensor. not much you can do except get a defouler.

 

^^ what he said...

misread the "megan" as mugen

 

If you didn't reconnect the Intake Air Sensor when you swapped intakes that'll throw a CEL.

 

well i decided to change things as they were so i bought a new cone filter ( kn) and put it again as a ssr and for my surprise the cel didnt appear, so problem solved
