APR Iridium Pro Spark Plugs

Featuring one of the strongest available materials for this type of product, APR Iridium Pro spark plugs help provide an ideal upgrade for tuned engines. They run cooler, resist pre-ignition, last longer than other materials with higher melting points, and require less voltage to produce a strong spark. The electrode is harder and stronger than other materials; can dissipate heat more easily; and is better protected from melting, cracking and other limitations found with standard models. These plugs are designed for use on tuned and high-performance vehicles that benefit from a 'cold' plug. They also pair nicely with APR ignition coils, where applicable. Order the APR Iridium Pro spark plugs recommended for your vehicle. Other features include: * Heat range 9 (similar to Bosch 3, Brisk 10, Denso 27, and NGK 9 ranges) * Melting point is higher than platinum (38 percent), copper (125 percent) and silver (152 percent) * Available in non-projected and projected insulator designs * Optimized electrode design for hard-to-ignite fuels (ethanol, etc.)

APR Lug Bolts

APR offers a variety of lug bolts in lengths and thread sizes to meet your needs. Unlike stock wheel studs, which only have a limited length, APR's extended lug bolts go together well with wheel spacers. Wheel spacers are designed to physically move the wheel further away from the hub for the desired offset needed to create the stance or look you desire, or clearance necessary to clear brake calipers. This typically requires longer bolts. Using longer style APR wheel studs will provide more thread engagement to secure your wheels tightly to their mounting hubs. Select the appropriate length and thread size APR lug bolts designed for your offset application.

APR A02 Flow-Formed Bronze Wheels

APR A02 flow-formed bronze wheels pay homage to several classic wheels in a unique design that is sure to turn heads. Central to the wheel is a classic 5-spoke pattern that has been hollowed out for weight savings and interlaced inside of a 5-spoke "Y" pattern that pays respect to the APR A01 wheels. The meshing together of these two iconic designs creates a snowflake pattern from decades past. APR A02s are flow-formed from A356 aluminum making them strong and lightweight, yet cost dramatically less than forged wheels. Finite Element Analysis (FEA) was used to reduce spoke width to reduce weight while providing the strength necessary to achieve a 720 KG load rating. Weight-saving pockets are cut behind the wheel face to reduce weight, too. Strong billet aluminum CNC-machined rings allow the wheels to be compatible with both common center bores, and won't wobble, crack, or crumble like other materials. The center caps are removable, upgradeable, and compatible with various OEM center caps. The lug bolts are compatible with OEM ball seat lugs, and the barrel has anti-slip machining features to prevent tire-to-wheel rotation. APR A02 wheels are offered in various widths, diameters, and offsets. Choose the proper fit for your vehicle.
