Our Hydropower hydraulic brake assist power booster fits 1954-55 1st series Chevy and GMC trucks and generates up to 1800psi of line pressure to the brake calipers. It is fitted with a POL or Wilwood master cylinder and adjustable proportioning valve. This kit is powered by hydraulic line pressure from the power steering pump. Firewall and valve cover clearance is equivalent to a 7" diameter vacuum booster. The firewall brackets are correct for 54-55 1st series GM truck applications.The average power steering pump puts out from 800psi to 1400psi line pressure. The Hydropower uses this to convert to pressure to apply against the master cylinder. This greatly improves stopping performance and driver feedback. These hydraulic power boosters can be easily installed on an existing vacuum booster vehicle or used to convert a manual brake setup to power with ordinary hand tools and average mechanical ability.

Fresh Air Upgrade for My 2024 Impreza
Installed this in my 2024 Subaru Impreza, and it fit perfectly—no issues. The air smells noticeably cleaner now, and it took less than 10 minutes to swap out. The carbon and HEPA filtration does a great job clearing out odors, dust, and pollen—definitely an upgrade over the factory filter. The build feels sturdier than the OEM version, though it does have slightly fewer pleats. Might mean it needs replacing a bit sooner, but for the price and performance, I’m fine with that tradeoff. If you’re looking for a quick, affordable way to improve your cabin air, this one’s a solid pick.

Well built, good fit.
I like it so well, I just bought two more to keep on the shelf for when the price doubles. Seems better built than oem, but I don't know how you can judge the filtration; seems good though.

Works Fine, Fits Fine
Size: (Pack of 1)
Seem to work and fit just fine and should be better than a cheap paper filter. They cost more but I change the oil on the 5's and the filter on the 10's so it evens out. Not going more than 10K on the filter. If you are only going to use the filter for 5K miles I would stick with the Toyota factory filter. I use the K&N filters on a 2017 Toyota Sienna and a 2018 Toyota Highlander. Both are V6
