KS Tech CAI - Stock Sized MAF Housing



Product seemed top notch at first. Intake had a pretty nice construction and I got the fancy red power coating. Looking back at it I would have left it chrome and just coated it with something to help reduce intake temps. Regardless, it seemed nice.


Had some frustrating issues getting the heat shield on. Just force it in and use an awl to get the self tapping screws started. It works.


Car feels a bit more responsive. Not much louder at all. Can hear the turbo spool up a bit and can hear the bypass valve a lot more.


Tuning wise, I can tell it helped up top in the rpm range. Just a heads up - you will need to slightly rescale your MAF despite claims (I suspected this anyhow). Otherwise, I was running about .5-1afr lean up top - which is bad in lay mans terms.

Filter sits right in here at the top of the compartment:




Sucker does through a high MAF code if I enter boost within 8 hours of a touchless car wash (no underspray either). Who knows. 'Tis a CAI, ha.
