2011–2025 Subaru Forester / Subaru Impreza / Subaru WRX / Subaru STI / Other compatible models with headers and high-heat engine modifications

Part #: AC008

Overview

If you’ve upgraded your vehicle with headers or other high-performance engine components, you know that excessive under-hood heat can pose a serious threat to your spark plug boots and wires. CORSA Performance's Titanium / Spark Plug Boot Covers are designed specifically to address this issue, providing a reliable barrier against extreme heat that can cause boots to burn, crack, or harden over time. These covers are an essential upgrade for enthusiasts who want to protect their ignition system and maintain optimal engine performance.

Constructed from high-temperature resistant basalt fiber material and treated with a proprietary coating, these boot covers are engineered to withstand the intense heat generated by headers and other performance modifications. They help prevent heat-related damage, ensuring your spark plug wires stay flexible and functional, which translates into more consistent ignition and smoother engine operation. Whether you're a daily driver or a serious performance enthusiast, these covers offer peace of mind and enhanced durability under the hood.

Key Features

Designed with durability and heat resistance in mind, the CORSA spark plug boot covers feature:

• High-Temperature Basalt Fiber Material: Made from a non-flammable, heat-resistant basalt fiber that effectively shields spark plug boots and wires from extreme under-hood temperatures.
• Proprietary Coating: Treated with a specialized coating that enhances heat resistance, prevents burn-through, and prolongs the lifespan of your ignition components.
• Universal Fitment: Compatible with a wide range of vehicles equipped with headers or high-performance exhaust systems, including Subaru models from 2011 to 2025.
• Easy Installation: Designed for a straightforward, bolt-on upgrade that requires no modifications or special tools.
• Non-Flammable & Safe: Made from non-flammable materials to ensure safety in high-heat environments, providing peace of mind during spirited driving or extended engine runs.
• Protection Against Cracking & Hardening: Helps prevent the cracking, hardening, and deterioration of spark plug boots caused by prolonged exposure to heat.

Construction & Design

The CORSA spark plug boot covers are crafted from premium basalt fiber, a material known for its exceptional heat resistance and durability. The proprietary coating applied to the fiber enhances its protective qualities, creating a barrier that reflects and dissipates heat away from the spark plug wires. The covers are designed to fit snugly over the boots and wires, ensuring a secure fit that stays in place even under demanding conditions. Their lightweight construction adds no unnecessary bulk, maintaining easy access for maintenance or inspection.

Performance & Benefits

By installing these boot covers, you’ll notice improved protection of your ignition system from heat-related damage, which can lead to more consistent spark delivery and potentially better engine efficiency. The high-temperature basalt fiber helps keep your wires cooler, reducing the risk of misfires or performance drops caused by heat-induced deterioration. Additionally, the covers contribute to a cleaner engine bay appearance and can help extend the lifespan of your ignition components, saving you money on replacements over time.

Installation & Fitment

The CORSA spark plug boot covers are designed for a simple, bolt-on installation. They fit directly over existing spark plug boots and wires, requiring no cutting, drilling, or special tools. The covers are compatible with most vehicles equipped with headers or high-heat engine setups, including Subaru models from 2011 through 2025. No tuning or modifications are necessary—just slip them on and enjoy enhanced protection against under-hood heat.
