This oil pan works with almost all headers and all are fit and leak tested before leaving Killer B Motorsport. There have been reported issues of fitment issues with some Invidia headers, but not all.
Each pan comes with an OEM sized drain port as well as one 1/2" NPT Port. You will need to get a plug for the NPT port if you don't plan on using a quick drain valve or anything else.
OEM Belly pan will need to have a small piece trimmed on some models.
Turbo EJ20 engines will need to change to the STi dipstick and tube or simply mark the old dipstick with a new full mark.

Quality is top shelf but installation is difficult. I paid to have it installed as I didn't want to goof up and suffer oil leaks. My installer finally go it to fit with difficulty. Totally problem free once installed

Can't think of a reason not to go with Killer B! As said before quality is obvious over OEM and other aftermarket stuff out there. USA, USA! And a big thank you to RSD for wonderful service!
Much better quality than OEM
Tairy Hesticles 3 years ago
It doesn't take a mechanical engineering student like myself to see that the quality of the Killer B pan is vastly better than the OEM pan. Not only is it perfectly tig-welded together, but the overall thickness and construction of the pan is WAY better. I even see that the mating surface was slightly oversized to give a better, long-lasting seal. Fitment was exactly perfect, along with the baffle and oil pickup I also installed. Instructions were a little off, but it's because my car was a 2012 sti and the instructions were for an older one. Only difference was you have to temporarily move the air pump to get to the oil pan dipstick bolt that's on the driver's side head (underneath air pump). Make sure to temporarily remove the driver's-side OEM header heatshield and lower header bolt, as they'll be in the way when installing the pan. You can put them back on when the pan is on there. A+ quality overall.
Awesome oil pan

Thai is a very high quality oil pan. All of the welds are done very well and is much stronger than an oem oil pan. Installed with pick up tube and baffle plate, everything was included and looks great. One thing to know is if its going on an 02-04 wrx then you'll need to get a new dipstick from a 2.5( the one with a hook handle) or your oil readings will be wrong and could cause issues.

Q: Gasket skillgun7411473 10 months agoAnswer
Is there any sort of gasket out there or do I just use gasket maker like they do from the factory?
A: This is designed to use the Subabond from factory.

A: There is no traditional gasket needed. Threebond, HondaBond, FujiBond and appropriate Permatex products will do the job just fine. Be sure the mating surfaces are clean and follow the instructions for set and cure times.

Q: sti dipstick AND tube? hella flush is hella stupid 1 year agoAnswer
I understand you need a sti dipstick for turbo ej20 motors but do you need the tube too? I thought they were the same? Also, it can be any year sti right? Thanks
A: The OEM part numbers for 02-07 WRX and STI tubes are the same, so you don't need to change the tube. The dipstick can be from a 04-14 STI or 06-14 WRX.
