HOLDS ANY BOOST LEVEL - Cars with an ECU tune that increases boost levels will enjoy this part as you will never have to worry about it leaking under boost. The BOV is designed in such a way that the boost pressure pushing it closed is greater than the pressure trying to open the valve under boost. This means that 10psi, 20psi or 30psi of boost is no problem for it to handle!
LONG LASTING - Less is more! The ALTA CRV consists of four very simple purpose built parts. The diaphragm and spring are the same items used on the high tech Borg Warner EFR turbochargers, which means they are meant to easily handle extreme conditions and not fail. This is one of those parts you install and never have to worry about again.
GETS RID OF CHECK ENGINE LIGHTS - There are many Check Engine Lights and Diagnostic Trouble Codes that start to appear as your stock CRV ages. The P28AA (Compressor Bypass Error), P2c91 (Possible Seized Compressor Bypass), P2c90 (Compressor Bypass Seized/Closed), are all very common to see on cars that have more than 50,000 miles on them. These codes all appear because of the many faults with the OEM part. Getting rid of your stock CRV can do many good things for your car, such as eliminating turbo-damaging compressor surges, eliminating DTCs/CELs for faulty or sticky CRVs, and improving both drivability and power!
THICK DIAPHRAGM - A common problem with the stock CRV diaphragm is ripping at higher boost levels and normal wear and tear. The stock part is made of silicone and rubber with no reinforcement to it. So when it starts to fail, it fails quickly. The ALTA CRV has a high quality rubber diaphragm with reinforcement to keep it lasting for the life of your car.
