Instead of just cutting off the plugs and leaving loose wires when doing a TGV (tumble generator valve) modification, it's better to cap the plugs with these blanks. This cap set from iWire allows for future expansion of features while still protecting the TGV plugs from electrical shorts, moisture, and corrosion. Plus, it looks better than a messy ball of electrical tape.
Set of either four or two plug caps, depending on model. The four-plug set fits 2002-2006 Subaru WRX and WRX STI. The two-plug set fits 2007 WRX and WRX STI. (Works on Legacy and Forester models, too. Call us if you need help.)
