ECU tuning module

The APR Valve Stem Caps provide a stylish and subtle enhancement for your vehicle's wheels. Sold as a set of four, these caps are constructed from durable aluminum and feature a sleek black finish. Each cap is meticulously engraved with the APR logo, adding a touch of brand-specific flair to your valve stems. These valve stem caps are designed with a focus on aesthetics and simple installation. The aluminum construction ensures longevity, while the black finish complements a wide range of wheel designs. The "classy design" aims to elevate the look of your valve stems, a small detail that can make a noticeable difference. While the product description humorously suggests potential horsepower gains, it also clearly states that "HP gains are unconfirmed." These valve stem caps are primarily an aesthetic upgrade. The product is compatible with "Most APR ECU/TCU supported vehicles - Audi / VW / Porsche / Bentley" and is also described as having "Universal Fitment" by some retailers, indicating broad applicability across many vehicles, particularly those from VAG brands. As with many aftermarket automotive products, it's important to note general advisories. While not specifically stated for this product, APR generally notes that "Products that affect emissions, and do not carry a California Air Resources Board Executive Order, are not for sale in California, USA." Additionally, "Some products may not comply with local laws, and some may affect parts of the manufacturer's warranty."
