Ferrari 355 Exhaust By-Pass Valve Kit (Incl. Sealing Rings)
This valve has been constructed specifically to address problems previously associated with failure of the OEM unit. The OEM valve typically failed in the ‘closed’ position, resulting in high exhaust back pressure, which resulted in engine and/or header heat damage. The CAPRISTO replacement valve has been redesigned in a different configuration. Should a vacuum and or electrical failure occur, the valve automatically reverts to the open position, relieving excess back pressure. This protects engine components and exhaust headers from heat damage.
The CAPRISTO valve is supplied with the necessary vacuum tubing and required electric solenoid valve. All parts fit into the original mounting place with no modifications needed.This valve now ships WITH sealing rings. No need to purchase the seals separately.
The system is fully compatible with the optional CAPRISTO remote control. The remote control gives the driver the option to open the valve at will, with the touch of a button. A more comprehensive description of the standard remote control for the valves is available under our remote controller section.
The Standard Remote Control Kit IS NOT INCLUDED in this package.
Note to installer:
As the CAPRISTO valve uses vacuum to close (OEM use vacuum to open) please ensure that the vehicle generates a vacuum pressure of at least 0.7 to 0.8 bar or 10 to 12 psi. This ensures that the valve will close properly without any rattling. All vacuum lines and equipment relying on vacuum should be inspected if this vacuum is not generated by the vehicle.

Great value !
I have a 2016 Toyota Sienna , and every time i bring it in for service i am told i need a new engine and cabin air filter...i decided to buy this one for the engine filter last July...It is good quality and it took all of 1 minute to install in my car..The best part of this filter is it was less than $16.00 and the dealer was going to charge me $ 60.00 for the Toyota brand....I just put my 2nd filter in yesterday. took car in for service today and was told engine filter looks good....No more dealerships for filters...

Fits great on my 2014 Avalon 3
Fits great on my 2014 Avalon 3.5LV6. I changed filter every 20Kmiles (The first 2 Toyota filters were still looking good @20Kmiles). This GP075 filter has been in the car for 600miles. The throttle response is much better (more flow than OEM ?!). My last tank of gas shows >1MPG gain. I found myself backing off on the gas pedal quite often .. just need to reset my memory on how the car response probably. I also like how inexpensive it is ... so how do I take off a star in my rating ??? There are lots of (rubber molding) excess bits on the clean-side (none on OEM filter) ... what if one of them got sucked into the engine ???
