After years of witnessing people trying to fab cold air boxes, we finally developed a clean, functional, solution that has been engineered with airflow foremost in mind. We integrated a pair of computer designed velocity stacks with a modern remote air filter assembly. Designed it to fit both the early and late cars, by giving it clearance for the brake servo on the later or converted MGBs. Then supplied it with a modern air filter that can be fitted without any modifications. To take things one step further, the design is such that if the hole in the radiator diaphragm is enlarged, the air filter can be remote mounted behind the grille by using readily available flex hose, for full cold air intake.
