Pacific Performance Engineering Premium High-Efficiency Spin-On Transmission Fluid Filters
Pacific Performance Engineering recognized the need for better filtration for the hard-working Allison 1000 and 2000 transmissions, so they developed the Premium high-efficiency spin-on transmission fluid filters. These superior filters are designed to address the limitations of the standard "shorty filter". Inside the PPE double-deep spin-on filter is 2.72 times more filter media surface area. This increased surface area allows improved fluid flow and filtering. The double-deep filter traps particles down to 15 microns—that is half the size of what the standard spin-on filter catches, which helps to create a cleaner flow of oil to vital internal components, resulting in smooth, more responsive shifts. Do more to protect your Allison transmission and realize better performance. Don't come up short. Spin-on PPE's high-efficiency transmission fluid filters!
