Titanium intake manifold studs for Subaru WRX & STi TGV/Manifold

This set made for WRX and STI engines with TGV system. It works with TGV deletes and OEM TGV housings.

Consists of 8 long studs for tgv housing to engine head junction (we also offer the option of 4 short and 4 long bolts, it depends on TGV housing model).

Grade 5 titanium, rolled threads for extra durability and strength.

You may add 12x m6 bolts for manifold/tgv junction. We recommend purchasing these sets together as these bolts are very close when installed and can look good when installed together. A complete set consists of twenty bolts.

Standard length or extended bolt are available for systems where thermal insulation gaskets are used. Choose +5 or +10mm studs if you want to use thermal spacers between TGV and engine head to prevent heat transfer into the manifold.

We produce our own titanium thermal plates, check our store if you want to buy this product.

we also offer the option of 4 short and 4 long bolts, it depends on TGV housing model.

Fits different Subaru engines (EJ25, EJ257, EJ207 etc), send us your question if you are not sure which set do you need.
