not sure if this has been posted or not, but i borrowed it from ft
Ok here it is, hope it makes sense....
Why do I want to do this?
To be honest...I'm not sure, personally I'm building a track car and want as little clutter and crap in the engine bay as possible. Also the pulse air injectors have something to do with emmsions and probably economy, something I'm not to worried about as the car is to be used on track.
Some people say theres a performance gain but I'm not convinced but for a total of £4.70 and about 30mins work you can't go wrong really.
What do I need?
Spanners/sockets/toolkit
4 x 6732263 - Copper washers (see pic below)
4 x 1008597 - Blanking Plugs (see pic below)
What do I need to do?
ok you need to start by removing the MAF sensor and inlet/crossover pipe so your engine now looks a bit like this (only less blurry and probably cleaner!)
Once thats removed you also need to remove the fan, you can do this by removing the 10mm bolt from the top mounting. It's easier to get out if you unclip the starter motor wiring and fan wiring from it first so it doesn't catch on the water piping nearby.
Next remove the manifold heat shield, first undo the 2 8mm bolts holding the metal water pipe in place and then theres only 4 bolts - 2 into the head and 2 into the manifold to get the heatsheild off. You can now see what we're trying to remove:
Then it's just a case of getting a 19mm spanner and undoing the pipes 1 by 1....if your car is anything like mine then they are probably a bit difficult to remove so I decided to get a 19mm 6 sided socket on them. The pipes are very thin and cut easily...as you can see:
To remove the pulse air piping follow the 2 metal pipes down towards the starter and you'll see a big black box bolted to the block infront of the crank position sensor. Remove the 2 10mm bolts and unplug the vacum hose then carefully remove the whole assemby making sure you don;t damage the radiator.
This is what we've removed...you can see the pipes that go inside the mainfold here:
This is it all removed:
now all you need to do is get the 4 washers and blanking plugs and an 8mm allen key and screw them into the holes in the maifold.
Also, remember that vacum hose you unplugged? All you need to do is follow it back to the solonoid on the bulk head and cut the pipe short, then all I did was block it off with a bolt...If anyone has a better suggestion then please let me know.
And in true Haynes manual fashion......re-fitting is the reverse of removal!
