If you have a failed or failing DISA valve O-Ring, air leaks into the intake andcauses your vehicle to idle rough or misfire. You can spend $200 to $300 for
the complete valve at your dealer or spend less than $4 and 15 minutes
in your garage.
As a BMW enthusiast and avid DIYer when I needed to replace my disa
O ring, I did my research and I was amazed at the many different types
of o rings and the cost of the o rings. There was also a lot of misinformation
that people were representing. There are many good sites on the o rings
and their materials and uses. Based on all of this, I decided to support the
community and buy a large quantity of the best material and offer them
at a reasonable price.
The encapsulated PTFE w/ Viton Core O-Ring meets or exceeds the OEM
specifications. Dupont specifically made Viton for automobile and airplane
engines. While other products may be slightly better rated in a certain
property, all pertinent properties for your application should be looked at.
Properties such as tensile strength, compressibility, abrasion resistance,
etc are just as important as temperature. While other materials may have
marginally better temperature properties than Viton, they do not have better
ratings for all the important properties.
All O-Rings are brand new.
