Works with common and custom top-mount intercoolers

It has been designed to work with all common top-mount intercooler kits. The concentric design allows the elbow to be rotated 90 degrees at a time to allow forward/rear/left or right facing. So whether your intercooler kit is off the shelf or a custom job, this elbow gives the lowest possible profile for maximum clearance under the intercooler. The adaptability makes the TD42 Intake Manifold suitable for a range of intercooler setups.

Tillix's ridge machined finish prevents hoses from popping off under pressure 

The inlet has a ridge machined finish surface to ensure maximum bite into the silicone hose. This helps prevent hoses from popping off … unlike with smooth or poorly finished surfaces on other intake manifold elbows. When using a 1HD-FTE forward facing manifold inlet, this feature ensures reliability.

Smooth or poorly finished surfaces are a leading cause of turbocharger failure due to a sudden overspeed event when the compressor becomes unloaded. This is why Tillix have taken the time and expense to incorporate a ridged machine surface finish on all of their high performance intake manifold elbows that can be subject to very high boost pressures. This is critical for the performance of the 1HD-FTE forward facing manifold inlet.

Other similar products use a simple cast ridge at the end of the tube, which works ok at low and moderate boost pressures but have been known not to perform at boost levels above 30PSI.

3 boost reference points

Tillix's intake manifold adaptor elbow is manufactured from cast aluminium and has three 1/8th BSP ports for boost reference points to attach a compensator, boost gauge as well as a spare. These features make it a versatile component of the TD42 Intake Manifold.

Comes with:

- Stainless Steel Cap Screw Bolts
- Boost Reference Adaptor
- Block-off bolts
