Not sure if this has been done before, i've never seen it, but it seems a pretty obvious mod. I took a 2 lamp grille, and a 4 lamp grille, chopped out the same section from each, bonded it back together, a quick rub down and rattle can job, and voila, a 3 lamp grille.



I will have a short length of large diameter aluminium hose inside to direct the air straight from the lamp hole to the air filter.
