R35 Ignition Coils – Stalks & Boots
 
In Stock – Ready to Ship Immediately
 
Upgrade your R35 coil setup with Ichiban Engineering’s custom short R35 ignition coil boots, available for both the Mitsubishi 4G63 and Toyota 1JZ / 2JZ engine platforms.
 
These precision-engineered stalks and boots are designed to perfectly fit each platform, ensuring proper spark plug sealing, optimal coil height, and reliable ignition performance under any condition. Unlike the OEM R35 coil boots — which often fail to seat correctly on non-R35 heads — our custom versions guarantee a secure seal, strong spark delivery, and a clean OEM-like fit under factory or billet ignition covers.
 
Developed using state-of-the-art 3D scanning, each variant (4G63 or JZ) has been digitally modeled directly from the engine head to achieve an exact fitment, with no trimming or modification required.
