Installation Guide

Installation is straightforward and can be completed in under 30 minutes with basic hand tools:

  1. Locate the factory boost solenoid near the turbocharger on FA engines
  2. It's accessible from the top of the engine bay
  3. May require removal of intake for easier access
  4. Disconnect the electrical connector by pressing the tab and pulling gently
  5. Disconnect the vacuum lines, taking note of their orientation
  6. Remove the mounting bolt(s) securing the solenoid
  7. Install the new solenoid in the reverse order
  8. Ensure vacuum lines are reconnected in the correct orientation
  9. Secure the mounting bolt(s) to factory torque specifications
  10. Reconnect the electrical connector until it clicks

Pro Tip: While no ECU reflash is required for stock applications, we recommend pairing with an aftermarket boost controller for modified setups to take full advantage of the enhanced performance capabilities.

International and Special Shipping Considerations

  • International orders are subject to higher shipping fees. If you would like to review your shipping cost, email us at sales@jdmuscleusa.com with your full address and items you plan to purchase.
  • In some cases, shipping costs may be incorrectly calculated for international or oversized items. We reserve the right to adjust the shipping fee and will work with you to negotiate a fair cost if needed.
  • Customers can challenge and request a review of international shipping fees, and we’ll do our best to find a lower rate where possible.
  • Customs Fees & Import Taxes: The shipping charge you pay does not include customs fees or import taxes. These charges vary by country and are the customer’s responsibility. Please check with your local customs office for more details before placing an order.
  • Shipping Cost Adjustments: Shipping rates fluctuate, and while we strive to provide the most competitive rates, there may be instances where the shipping cost you paid is significantly lower than the actual cost. In such cases, we reserve the right to request the difference to ensure we cover our basic expenses. We appreciate your understanding and will always aim to keep shipping costs as affordable as possible.

Freight Shipping Guidelines

  • Freight shipments require you to be present at the time of delivery.
  • The delivery driver may provide a delivery receipt (Bill of Lading). It is crucial to inspect the shipment before signing.
  • Carefully check the packaging for any visible damage (dents, punctures, rips) and notate it on the Bill of Lading.

Failure to document damages before signing the Bill of Lading will void any claims for refunds or replacements.
