CC Mac Posted July 27, 2017 Share Posted July 27, 2017 I am a new Z member. With one eye on mods,I have seen references to plenum spacers. Could someone tell me what they are for and what are the benefits, also how easy is the mod. All the best Mac. Quote Link to comment Share on other sites More sharing options...
Stutopia Posted July 27, 2017 Share Posted July 27, 2017 The plenum spacer mod you see on here is an insert that raises the upper plenum approx 8mm, it deals with a perceived design short fall where one cylinder gets less than optimal air. It's one of the classic 350z breather mods (along with exhaust, high flow cats, de-cats) that are done prior to an up rev remap to squeeze a few more ponies out the engine. Here's an example - https://h-dev.co.uk/product/h-dev-350z-intake-plenum-spacer-kit-vq35de/?v=79cba1185463 - shop around the traders on here, there is bound to be a deal to be had somewhere. https://www.torqen.uk/118-plenum-spacers https://www.tarmacsportz.co.uk/nissan/nissan-350z/motordyne-nissan-350z-5-16-basic-plenum-spacer.html Quote Link to comment Share on other sites More sharing options...

CC Mac Posted July 28, 2017 Author Share Posted July 28, 2017 Thanks for the info. I think mine is a standard 2006 gt apart from a Cobra stainless exhaust. I might go for a re map at some stage but I think this mod should be done first. I probably won't bother with cats as I don't want things getting too expensive. How much does it usually cost to fit the spacer and can you recommend anyone near Merseyside and North Wales for this and the re map. All the best Mac.
