Just upgraded my 2wd to green injectors, 3bar map sensor, 31 actuator, big cooler, big filter and a stage 3 chip just waiting to get it set up now at sitech hopefully in the next few days but I've seen people going on about these different manifolds one of them being the sweedish plenium, what are these like and is it worth changing my standard one for one of these. I've seen one advertised and just thought hmmmmmmm. Lol cheers.
