This photograph documents an ARP (Automotive Racing Products) cylinder head stud kit, part number 218-4703, for the Mazda 2.0L FS-DE 4-cylinder engine, apparently photographed for a for-sale listing dated 2-2-2012 with handwritten forum usernames (Probetalk.com / Mx6.com, 94MX6LSZE / 93MX6LSZE). Shown are the ARP retail box, the black head studs, nuts and washers, an ARP Ultra-Torque Fastener Assembly Lubricant packet (part # 100-9908, .5 oz), an ARP sticker, a warranty notice slip, and the official installation instruction sheet. The instructions detail the installation method: verify part number, clean and chase block threads (ARP Thread Chaser 912-0005, M11 x 1.5), use thread sealer if studs enter a water jacket, install studs hand tight, then lubricate threads/nuts/washers with ARP Ultra-Torque lubricant. The preload recommendation is to tighten the nuts in three equal steps to 90 ft-lbs using the supplied lubricant. A Bolt Torque Sequence diagram shows the numbered tightening order across the 10 head stud positions (8-4-1-5-9 top row, 7-3-2-6-10 bottom row). ARP contact info (Ventura, CA; 805-339-2200; www.arp-bolts.com) is also visible. The box label suggests 96/02 applicability for the FS-DE engine.
