water pump

--
belt tensioner
cam seal x4
front crank seal x1
oilpump o ring x1
oem coolant





also, are there any performance modifications that can be made while everything is taken apart?

 

you got pretty much everything covered in the list but I have never replaced cam seal x4=left
front crank seal x1, oilpump o ring x1, usually they never leak unless you got a oil leak going on, let me know if you need someone to take care of the job for you we are newly opened SUABRU shop in SANMATEO 308 7th ave hit us up, look us up on yelp Boxer specialist
