Just take one look at the plastic molded stock turbo inlet and you will see how it's pancaked design chokes airflow and robs your MS6 of its full performance potential. The ATP turbo inlet pipe for the 06-07 Mazdaspeed6 is constructed from full 3" stainless material to allow more air intake volume, giving your speed6 quicker spool and less intake turbulence. Specifically designed to handle the intake demands of a big Garrett turbocharger, the ATP turbo inlet can also be used to increase flow and maximize power on the stock turbo with the available reduction coupler. Silicone couplers available in red, blue or black. Please specify if you need a 2" stock or 4" Garrett coupler when ordering (call for more details).
