wilo Posted July 12, 2016 Posted July 12, 2016 (edited) nearly ready to buy a plenum for my 04 DE . Looking about iv noticed some say 1/2 inch .others say 5/16 or 8/16 . can someone please explain which i need and what the differences are ...tia seen these ..... Edited July 12, 2016 by wilo Quote
davey_83 Posted July 13, 2016 Posted July 13, 2016 Most go with the 5/18, they all do the same job of increasing air flow/pulses to all cyclinders as the front two in standard form receive less due to design - good rated engine mod. Quote
brillomaster Posted July 13, 2016 Posted July 13, 2016 the thicker ones may not fit under a strut brace without some spacers, and then even if the strut brace fits, the bonnet may not close! 1 Quote

Toon Chris Posted July 13, 2016 Posted July 13, 2016 You only need the spacer and screws. The second picture you post includes a gasket if you are removing and replacing the entire plenum. Not really sure why you would do that when you only need to take the top half off, fit the spacer and replace the top. I think some spacers have a thermal layer or are made of a thermal material that helps to stop heat-soak from the engine (the first one says this in the blurb). Possibly you get a separate thermal gasket for the plenum as a whole on the more expensive pack? That's a complete guess More likely its just stuff you don't need. You get what you pay for. Contact a trader from the forum who will have a decent quality brand they can offer you, like Motordyne. 1 Quote

wilo Posted July 13, 2016 Author Posted July 13, 2016 okay so iv now found a supplier for the plenum ...so my next question is .... if in attempt to fit the plenum my self , which instant gasket brand is recommended with the motordyne kit ? also whould i need to order any other bits to do the job ie throttle body gasket? Quote
ZMANALEX Posted July 13, 2016 Posted July 13, 2016 Do not use Instant gasket or any other sealer for that matter. The MD spacer is fitted dry and no other parts should be required. 2 Quote

jnoz Posted July 15, 2016 Posted July 15, 2016 (edited) I'm in the progress of making some of these. So really glad the thread came up! How much do the gaskets cost for the intake? Wow, that linked spacer is £253.18! Edited July 15, 2016 by jnoz 1 Quote

Brimstoneboy Posted July 15, 2016 Posted July 15, 2016 Might want to invest in a torque wrench if your heavy handed, if you ain't got access to one ,it is very easy though took about a hour for me to do and I'm pretty useless round cars . Google motordyne plenum instal should find a link for instructions can have a read before it comes . Sent from my iPhone using Tapatalk Quote

davey_83 Posted July 16, 2016 Posted July 16, 2016 should see decent gains over standard with those mods prior to remap also Quote
jnoz Posted July 23, 2016 Posted July 23, 2016 My skunk spacer arrived! It turned up, and it's made from PLASTIC! Well gutted for the price. I'll be making alloy ones. Hope it goes okay! Need to find how I will gasket it. Plenum gaskets cheap enough surely. Quote
davey_83 Posted July 23, 2016 Posted July 23, 2016 is there not at least one gasket attached to the plenum spacer from box? Quote
jnoz Posted July 23, 2016 Posted July 23, 2016 (edited) yes. there is. but im going to make my own spacer. but this one has a rubber seal integrated within the spacer, rather than being just a separate gasket Edited July 23, 2016 by jnoz Quote
