Exhaust valves.
Hi,
I will replace my exhaust Valves. Do you have any recommendation, which product (brand) is good? Original Valves are from TRW, but I saw burned TRW valves on my friends 911. I heard couple of rumors, that lately TRW have problems with quality. What are alternatives, maybe Intervalves? Sodium should be in Valves for better heat dissipation. regards |

IV are pretty good but with any inspect the quality last set of TRWs I had the stems were so nicked up I couldn't use them. AE I used a few years ago were also good but quality seems to change overnight on these things so don't be afraid to send them back.

Get some Del West valves if you're concerned about quality. Price (titanium) may make your heart skip a beat, but they are some of the best you can buy.
Intervalves are pretty good like cgarr said. Of all the aftermarket affordable brands we've seen, they seem to have been the most consistent in terms of quality.
