• Fluorosilicone O-Ring for BMW 330CI - Tuesday, May 28, 2024
  Great purchase, just what I needed. Shipped immediately. Received in 2 days with slightly upgraded shipping. In time to put the car back together with great success. The initial shipping information indicated a week to receive. I sent a note and GAS responded immediately that their shipping notice represents standard shipping, not expedited. He said it would be there in 2 days and it was! Thanks so much for your help. Product fit was perfect.
• Preventative Maintenance for 2004 BMW 330i ZHP - Saturday, February 3, 2024
  Been doing preventative maintenance and refresh on my 2004 BMW 330i ZHP with ~150,000 miles. Noticed that the DISA still had its original molded seal, which the previous owner had wrapped it in Teflon tape. The engine has been running fine, but I went ahead and ordered the 2-pack of silicon o-rings for peace of mind. The installation wasn't difficult at all. The most tedious part is picking the old molded seal out! It's nice that they include the pillow-pack of lubricant for the o-ring. Everything went back together easily and the engine is running smoothly. Thanks!

• Fixes uncommon vacuum leak for 2004 BMW X3 3.0L M54 - Monday, May 31, 2021
  The Fluorosilicone DISA O-Ring really helps seal the DISA valve into the intake manifold. When properly installed, it stops an overlooked and recurring vacuum leak from the DISA valve. This also helps to eliminate the DISA valve's possibility to cause the "System too lean" P0171 and P0174 codes from reappearing on an OBD2 scanner. This O-Ring is strongly recommended to replace the stock custom molded gasket on the M54 DISA valve.
