The OEM pickup screen is crimped in a retainer and that assembly is spot welded into the pickup ‘can’. There are a couple of flaws with this process. One is that the screen is creased where the retaining ring is crimped over it. The other is the spot weld process embrittles the screen. Killer B pushed on the screen of new OEM pickups and several popped wire strands without a lot of effort.
Killer B is being known for making some of the best Subaru performance oiling products money can buy, addressing this was right up their alley. Of course, they put their own spin of improvements on it, besides the obvious, they had to be made to assure "set it and forget it" reliability that comes with Killer B products.
The obvious big change is the tube has no bend. No bend means no restriction and even better coming from the OEM tube because it uses a more restrictive pinch bend. The I.D. of the tube has been increased as well and so has the O.D. thickness. The angle of the tube points it directly at the inlet into the block. Like the Killer B EJ engine Ultimate Oil Pickup this one too uses a screen to match the OEM spec opening size of the mesh, but they also use a higher strength screen material. The screen area has been increased over 31% which reduces the restriction and stress on the screen. The Killer B screen is lightly pressed and welded into place assuring the wire does not get stress or heat damage. TIG welding throughout assures proper weld penetration and quality. The material is 4130 alloy steel to further provide an increase in strength over the brazed stamped steel OEM version. Every Killer B unit has been pressure tested to 150psi over the face of the screen without issue.
