EMPI's HPMX carburettors are some of the best in the industry. In a head-to-head comparison, the HPMX was able to match and even surpass the performance of their Weber counterparts. Best of all, the HPMX is fully compatible with all IDF components, such as jets, emulsion tubes, etc. EMPI tests and adjusts each and every one of their carburettors at their Anaheim California facility prior to shipping.
