PERRIN Performance CNC Billet Aluminum TGV DELETE for 2015-2019 WRX (Black)
Part # PSP-ENG-221BK
PERRIN TGV Delete plates have been designed to improve the airflow by removing the butterfly mechanism in the factory tumblers. The OE tumbler valve tends to fail after a while so in a sense, this will save you money down the road with simplified intake tract. There have been attempts to try and drill out the factory butterflies and often times, you will deal with a huge hassle such as metal shavings everywhere, tons of broken dremel bits, and lots of time.
Save yourself the pain and just go with a professional and proven product brought to you by one of the best in the industry. PERRIN TGV delete plate is machined with even the smallest details such as the fuel line recess so that you won't cause the line to stretch and not have clearance.
Here are the details:
- CNC machined from aluminum
- Anodized black finish
- Installation required use of OEM hardware
- Improves airflow
- Great upgrade for those looking to make big power as OEM tumblers can be a restriction
- Sold as a pair
