1.8T High Flow Transverse Manifold

One of the biggest restrictions of the standard 1.8T engine is the exhaust manifold. These high flow manifolds will greatly improve the exhaust gas flow and help to free your 1.8T up at high revs. They flow more than 50% more than the standard items which will result in more bhp and torque. The quicker flowing manifold also keeps the exhaust temperatures down which not only reduces wear on the turbo but will also allow for more advance timing.

Fits K03, K03s and K04-001 (not K04-02x series) standard fitment turbos and other turbos that utilise the standard K03 exhaust flange.

Applications:

Audi TT 1.8T FWD 150bhp
Audi TT 1.8T Quattro 180bhp
Seat Leon 1.8T 150/180bhp
Skoda Octavia 1.8T 150bhp
Skoda Octavia VRS 180bhp
VW Golf 1.8T (Mk4) 150bhp
VW Golf 1.8T (MK4) 180bhp
VW Bora 1.8T 150/180bhp

Supplied with High Tensile turbo mounting bolts. We recommend you replace your gaskets with original VAG items.

Picture 2 shows the standard VAG manifold compared to the High Flow manifold. You can clearly see the difference in size.

Power increases vary depending on other modifications. We have seen an increase of 19bhp on a 1.8T setup using an aftermarket turbo which was previously utilising the standard K03 flange/manifold.
