I have a 74MM IPD plenum and want to replace the oring between the plenum and the TB. I know that the TB is the 74mm 997 TB (997.605.115.01), does thet mean I just need to get a 997tt o ring or can it only be sourced from IPD?


Many Thanks

 

I think that's a safe bet, my friend.

 

I asked this question of IPD directly, they didn't answer the question but offered to send me one free of charge. If only more companies had that kind of customer service.

 

Based on the price of the plenum, one would bet they have plenty of margin.
