It keeps the EGR clean that is very prone to fail and clog and it also keeps dangerous hot exhaust gases from destroying your motor. Cool air in and NEVER a CEL...issues are completely resolved...!This doesnt add power tho right? Just curious. It just adds fresher air?
Picked this up from NSWDoc and installed it. Pretty straight forward. I found the positioning of the air filter with a straight adaptor didn’t work for me due to some other wiring and brackets on the block so I added a 90 degree fitting.
