UPGRADED DIVERTER VALVES
Reason: Hearing the pfft sound when I shifted under heavy boost left me wondering if I might have a problem with my DV’s.
|Hearing the pfft sound when I shifted under heavy boost left me wondering if I might have a problem with my DV’s.
|I was not noticing any loss of boost through my boost gauge, but these parts are known to fail frequently on the S4’s so I began to research my options.
|I elected to go with the 710N. In terms of cost they were the least expensive and I had no reason to think any of these DV’s provided a performance gain over any other. Durability was another consideration, but with the significant price differential between the 710N’s and the aftermarket brands I could afford to buy several sets of 710N’s before I would reach the cost of one set of aftermarket DV’s.
|Besides eliminating the pfft sound I have not noticed any difference in the way the car drives with the new 710N’s installed. This does not surprise me. I am quite happy with this low cost replacement part.
|I pulled these off around the 50k mark to test them out. They were still holding up fine.
