This high quality reinforced silicone hose kit replaces the large air intake from the airbox to turbo plus the turbo coupler from the turbo to intercooler in the engine bay. The hoses fit all ST185 (5th Gen) Celica GT4 models except CS/RC models, which have two breather inlets in the centre of the large intake hose as well as one at the top of the hose. This hose only fits standard GT4 models which have one breather inlet in the centre of the hose and the one at the top, but if you don't need the second breather inlet in the centre due to modifications the hose will also fit a CS/RC model.

Hose Clamps:

The kit is available with a full set of hose clamps using the options above. The three types of clamp we offer are shown below, but not all options will appear for some kits due to size limitations:

Worm-Drive Clamps, Spring Clamps and T-Bolt Clamps

Spring clamps * Not available for this kit *

Worm-Drive clamps have slightly less evenly distributed clamping force as the Spring type clamps, but they are still a good quality clamp and usually easier to fit/remove in the tight confines of an engine bay. Being 100% stainless steel they do not rust, so we recommend this type of clamp if you are concerned about the appearance of your engine bay.

T-Bolt clamps are the most heavy duty clamps we supply, and are also 100% stainless steel to prevent rust. However they are much more expensive and, like the Worm-Drive clamps provide a slightly less evenly distributed clamping force than the Spring clamps. For this reason we recommend using them for Turbo applications (intercooler/intake hoses) where high boost can cause hose blow-off's and the additional clamping force is useful. Some customers like to use T-Bolt clamps for all hoses on their vehicle however so we offer them as an option for most of our kits.

For some vehicles the original clamps can be reused so we also offer our kits without clamps, but please be aware our silicone hoses are slightly thicker than the standard hoses so in some cases the original clamps may be too small.
