02-07 WRX & STI Gauge Installation Fittings

These are fittings for installing gauges into your 02-07 WRX & STI. It is important to monitor your engine especially when modified. These fittings are a convenient way of installing temperature and pressure sensors so you can keep an eye on your Subaru.

GTSPEC 38mm Water Temperature Adapter

Installs in the upper radiator hose of the WRX & STI and offers a 1/8 PT fitting for a temperature sender, making adding a temperature gauge to your vehicle a simple task. Aftermarket water temperature gauges provide more accurate temperature readings then stock gauges. You must cut your upper radiator hose to use this product!

Notes:
This will fit most JDM 1/8PT gauge senders (i.e. Defi, Blitz, Apexi, and Greddy).
You will have to cut your radiator hose for installation.

GTSPEC "Sandwich" Oil Filter Adapter

Installs in the place of your existing oil filter on the engine block -- your oil filter then screws into the adapter. Features two 1/8PT fittings for multiple gauge senders (i.e. oil temp and oil pressure). This oil filter adapter from GT-Spec is one of the easiest ways to install oil temperature and pressure sensors on your Subaru WRX & STI.

Note:
This will fit most JDM 1/8 PT gauge senders (i.e. Defi, Blitz, Apexi, and Greddy).

Subaru Oil Galley Plug w/ 1/8PT Threads

This is a genuine Subaru part that installs in place of the stock WRX & STI oil galley plug, located on the top of the engine block, beneath the top-mount intercooler. This port is plugged from the factory, but runs right into an oil passageway, making it an excellent spot to hook up an oil pressure or oil temp gauge (or both if you purchase a tee fitting from your local hardware store). Sure beats using an oil filter 'sandwich' adapter!
