Hi Kev I didnt just mean your plenum I meant plenums in general, some people are saying that the new FG log type inlet is the way to go as it evenly distributes the air. To be honest after reading many other posts on here regarding the plenums and having spoken to Tony @ Tunehouse my mind is at ease with the plenums so I think my next step will be the plenum so I will be calling you shortly Kev as im looking to get Tunehouse boys to change over my valve springs in the near future so may as well complete at same time. Otherwise all I can say is great gear Kev, whole kit installed very easily, looks great and most importantly makes the power!!!!!!
