are there two or is it just one ? if its two then they replace the stock recircs ( like for like bolt on job ) which are located behind front bumper on drivers side.

P.S unbolt one at a time so that you put the vac lines back the correct way

it replaces the black rubber pipe going from the plenum (front left corner) basically you will need two straight couplers 80 mm ID or you could cut your old rubber pipe its up to you and two more jubilee clips then some vacuum pipe to pipe the valves up

Yep defo fits under the bonnet, replaces the rubber pipe that comes off the plenum.

You will need to remove and block off the standard dumpvalves.

Be prepared for irratic idel and car stalling every now and then if you are still running the air flow meters......it happens with vent to atmosphere dumpvalves.......doesnt cause any harm but gets annoying at times.
