1-Year Limited Warranty

Every SPOOLOGIC wastegate actuator is covered by a 1-Year Limited Warranty against defects in materials and workmanship from the date of purchase. Warranty coverage requires that the wastegate actuator first be shipped back to SPOOLOGIC for inspection. If SPOOLOGIC determines the failure was caused by a defect in materials or workmanship, the wastegate actuator will be replaced at SPOOLOGIC's discretion. Warranty does not cover damage from improper installation, incorrect vacuum line or electrical connection, use outside the listed fitment, boost or exhaust pressure beyond the wastegate actuator's rated operating range, tuning that exceeds safe operating parameters, contamination, corrosion from moisture ingress, cosmetic wear, or normal heat cycling marks. Warranty does not cover labor, shipping, towing, downtime, gaskets, hardware, or any other costs outside the wastegate actuator itself.
