Silicone Reinforced Hump Hoses

Silicone hump hose allows for expansion and movement between pipes. By allowing a little flex in things you have less chance of pulling connections loose and there is less stress on the rest of the piping. They also allow for slight misalignment between pipes. Specify color!

 Now available in Red, Blue and Black.

Silicone Vacuum/Boost Source Hose

Thick wall silicone hose withstands heat much better than the stock rubber hoses
Plus the pretty colors look dope and impress all the girlies ;-) 

For use as boost and vacuum hose, not for pressurized water lines. 
OK for coolant overflow and breather hoses.  NOT FOR FUEL LINES!!
For discount pricing, mix and match any size and colors for total length.


Black available in all sizes

Availability of Blue/ Red/Yellow/ Silver is limited  to the sizes below:

Red    10mm

Silver 10mm

Blue    8mm

Purple 6mm

Yellow 6mm

Yellow 4mm


Inside Diameter Price per Foot 
4mm $2.00
6mm $3.00
8mm $3.50
10mm $4.50

Tuning Tip: Red is a good color for all around performance, however with a big turbo blue gets upwards of 10 hp, unless you have stock cams, then only 5 hp. Purple is best for bottom end power, mix with red for excellent mid-range. For NT cars, shift all recommendations one hue towards a warmer color. Yellow hose should only be used on high compression NTs or turbo cars with welded differentials. Proper Sticker Tuning can be a successful work around for any of these concerns. ;-P


For kits that include enough hose to replace the vacuum hoses on the average DSM,

The stainless steel band features a beveled edge to prevent damage to the hose and your fingers! The knurled head bolt wont work loose and is grade 8.8 zinc plated steel.

These clamps have a fairly narrow clamping range so please check the outside diameter of your hose carefully.

Larson Colored Silicone Hose Kit. 

These colored silicone hoses withstand heat much better than the stock rubber hoses. The kit includes enough 4mm, 6mm, 8mm and 10mm hose to replace all the vacuum hoses, the coolant over flow hose, boost control hoses and blow off valve hoses to fit the average car. . 1G cars use a lot more 4mm hose so the price is a bit higher. They are not for use as water lines or fuel lines. You remove  each stock hose, one at a time and replace it with the silicone hose. You cut to length.

Available in Black, Silver, Red, and Blue. Specify color.
Sorry Yellow is discontinued 


  1G  Turbo, GVR-4  $49      1G NT $40      2G Turbo,$30

   2g Non-Turbo  $ 40
