California Prop 65 Warning: Operating, servicing, and maintaining your vehicle can expose you to harmful chemicals like engine exhaust, carbon monoxide, phthalates, and lead, which may cause cancer and birth defects. Minimize exposure by avoiding exhaust inhalation, idling only when necessary, servicing in a well - ventilated area, and washing hands or wearing gloves often.
How to use: First, make sure your vehicle's engine is turned off and cooled down. Locate the old MAF sensor position in your 2008 - 2014 Subaru WRX or STI. Remove the old MAF sensor carefully. Then, place the GrimmSpeed MAF Block Off Plate in that position. Ensure the O - ring is properly in place to create an air - tight seal. Finally, secure the plate according to the vehicle's specifications. Note: This plate is designed only for the specified Subaru models. Do not try to use it on other vehicles. When handling the plate, be gentle to avoid scratching the anodized finish. Maintenance: Periodically check the O - ring for any signs of wear or damage. If the O - ring is worn, replace it promptly to maintain the air - tight seal. Also, keep the plate clean by wiping it with a soft, dry cloth. If there are any stubborn stains, use a mild cleaner suitable for aluminum.
