This injector is the first stage high performance injector for the Mack E7 VMAC I & VMAC II engines built between 1991-1997. This injector provides between 10-15 percent increase for the 1991-1993 E7 300, approximately a 5 percent increase for the 1991-'93 E7 350 and 400, a 30 percent increase for the '94-'97 E7 300 and approximately a 15 percent increase for the '94-97 E7 325 and 350. On their own, these level one injectors provide substantial performance improvments, but when they are used with the Bixxton-Mack the performance is improved dramatically. These are reman injectors requiring that old cores be returned. CORE CHARGE: You will be assessed a core charge of $100 per injector at the time of purchase. However, when the cores are returned we will refund $100/injector to your credit card account. Feel free to call our parts department at 507-288-8038 with any questions.

Combined Shipping: On items that are sold with a shipping charge, we do try to combine shipping as much as possible, which saves money for both our customers and ourselves, if each item is paid for on the same date. Unfortunately, we cannot guarantee combined shipping if the orders and payments come in far apart, even on the same day. Orders that are paid for on separate days will probably NOT be combined.
