easier than the CAI, IMO.
just take out your current airbox, be careful with the mass air flow censor, take out the snorkel, and the the short ram is like 3 screws and 1 piece of plastic pipe. It takes less than an hour if you know what you're doing.
and all the parts are up high in the engine bay, it doesnt go below where the stock airbox is like the CAI, so everything is easily accessible. Hardest part is getting your current air intake out haha.
