Show original supplier description

The Motorsport Auto Performance Cold Air Induction is a racing-style intake system engineered to enhance power and fuel efficiency for your 1984-1989 Nissan 300ZX (Z31). The kit includes a 9" long by 6" diameter K&N High Flow Cone Filter and a 6" long by 3" diameter polished intake tube with beaded ends. It also comes with two stainless steel installation clamps for a secure fit. While the updated tube is polished, it may retain a slight "brushed" appearance that can be further polished or prepped for painting and other finishes. It is important to note that performance intake systems may not be street or smog legal in all areas. Customers should verify local regulations. A C.A.R.B. approved kit (part #11-2948) is available for those requiring specific emissions compliance.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
