anon_uk Posted September 27, 2017 Share Posted September 27, 2017 Hi guys, I am looking at a couple of performance upgrades that won't cost the earth. One of the origanals that seem popular is the IPD plenum with 82mm throttle for the 987.1. Does this provide a noticeable upgrade? £970 from Design911 plus fitting and a remap is not cheap for 10% increase. As a new I do not have permissions create posts in the wanted section, do many of these come up 2nd hand and what kind of price? Thanks Link to comment Share on other sites More sharing options...
crafty1 Posted September 28, 2017 Share Posted September 28, 2017 Unless your car has a freer flowing exhaust and cats then it's probably a waste of money doing the intake and remap at this stage. From what I am told the extra power in these engines is mainly released from exhaust and cats then work back from there. Link to comment Share on other sites More sharing options...
banjo Posted September 28, 2017 Share Posted September 28, 2017 although ive never done it you can buy a bosch 82mm throttle body for £116 from autodoc part no 99760511601 and a 911 intake/plenum for 55 euros from rose passion part no 99711041603 youtuber oval bore did this on his boxster. hope that helps Link to comment Share on other sites More sharing options...
anon_uk Posted October 10, 2017 Author Share Posted October 10, 2017 Hi guys, thanks for the replies. I did purchase the 82mm throttle body (99760511601) as I thought either way for the suggested setup or IPD I would still need that. Currently, I haven't ordered the 911 intake until speaking with the Porsche specialist as I would have him fit it anyway.
