Features

• Dry carbon fibre construction - manufactured using prepreg dry carbon fibre for a superior strength-to-weight ratio and premium surface quality versus plastic or wet-lay carbon alternatives.
• Engine bay dress-up upgrade - replaces the factory ECU cover with a premium carbon fibre unit, visually elevating the appearance of the GR Supra's engine bay and complementing the B58's overall presentation.
• Lightweight - dry carbon construction reduces weight versus the factory plastic cover, contributing to a minor overall mass reduction.
• Designed as a companion to HKS's GR Supra A90 dry carbon engine bay range - pairs with the HKS Dry Carbon Engine Cover (70026-AT016) and HKS Dry Carbon Cold Air Intake Box (70026-AT003) for a unified engine bay aesthetic.

Product Description

The HKS 70026-AT017 is a dry carbon fibre ECU cover for the 2020+ Toyota GR Supra A90 (B58), designed to replace the factory plastic ECU housing cover in the engine bay. Constructed from prepreg dry carbon fibre, the cover provides a significant visual upgrade over the factory unit - transforming the ECU area from a standard plastic component into a premium carbon fibre showpiece that complements the B58 engine bay's aesthetic.

The ECU cover is designed as part of HKS's broader dry carbon engine bay range for the A90 GR Supra, intended to pair with the HKS Dry Carbon Engine Cover (70026-AT016) and Dry Carbon Intake Box (70026-AT003) to create a fully cohesive carbon engine bay presentation. It can also be installed independently as a standalone upgrade. Installation uses the factory mounting points - no modification is required. The dry carbon construction also contributes a minor weight reduction versus the factory plastic cover.
