ESR kindly fitted one of these for me last Saturday.
I`m still grinning :teeth:
I can honestly say that they work and they work well. My car REALLY shifts now! This is the only mod that has made any appreciable difference to the cars acceleration. The pop-charger improved throttle response but the plenum spacer just makes it fly!
When cruising the improved torque at lower revs makes driving effortless and smooth, plus, bizarrely enough, the mpg has started creeping up. I have no idea why as I`ve been hooning it around but the mpg has gotten better by 1 mpg !
For the cost, easily the best mod you can have IMO.
