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.

This stuff really works fast and improves mpg like you won’t believe
Size: 300 Milliliter
I’ve tried many other types of fuel injector cleaners but this brand is amazing. I ran my truck down to less than a quarter of a tank of gas and poured it into the tank. I then drove 30 miles to an appointment and spent an hour in the appointment on the way home I noticed my mpg had gone up significantly. My truck tells me how many miles per gallon. I’m getting as I drive. I had gotten a code and I replaced the mass air filter and found a slight crack in an air hose, which I replaced that help with my code a little bit, but cleaning the fuel injectors with this product made such a significant difference. I just simply had a hard time believing it, but it’s true.
I’m done with all those other brands of fuel injector cleaners which never really seemed to help much if you really want an amazing experience give this product to try.

Perfect fit, no problems.
Style: Standard Air Filter
It fit perfect in my grandson's 2013 Subaru Outback. It went right in with no problem. And you can't beat the price. Will definitely purchase again.
