This pipe is known to be fragile and can break even on stock cars during track sessions. If you're considering tuning your engine, it's highly recommended to upgrade the charge pipe beforehand.\u003c\/p\u003e\n\u003cp\u003eMany aftermarket charge pipe kits for the B58 engine are available, but in our opinion, most are not properly designed. Many competitors use a basic design: two pipes joined by a straight reducing silicone hose. It's evident they haven't understood the importance of handling the thermal movement in this system. Such design is almost certain to cause problems with the hose popping off due to it does not allow movement from temperature changes. A common solution people think of is tightening the clamps more, but this will in most cases break the pipes since it will deform the clamping surface.\u003c\/p\u003e\n\u003cp\u003eBut we've taken a different approach at do88. For us it was clear the system needs a flexible connection in-between the two pipes which can handle the thermal expansion \/ contractions. Our solution is an aramid reinforced silicone hose with 3-humps. This hose design allow movement in any direction without folding or putting the connections at stress. To further strengthen our design the pipes have CNC-machined 6063 hose connection ends with 3mm wall thickness. These hose connections won’t deform even for overtightened hose clamps.\u003c\/p\u003e\n\u003cp\u003eOur charge pipes don’t only solve the durability but of course also improve the performance. We designed our pipes with a larger diameter and smooth mandrel bends to enhance the performance. The lower pipe measures 60mm (2 3\/8”) and the upper pipe 76mm (3”), they effectively reduce the pressure drop and cut down on turbulence.\u003cbr\u003e\u003cbr\u003eOur charge pipe, which connects to the throttle body by its CNC machined flange, has two 1\/8 NPT ports suitable for methanol injection or outlets like a boost pressure sensor. Additionally, we provide two 1\/8 NPT plugs for those who choose not to use these ports.\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"color: #ff0000;\"\u003eImportant Notice\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe space available for the charge pipe between the throttle body and the slam panel (the sheet metal part located over the radiators) is very limited on the G-chassis platform. In some cases, it may be necessary to grind the edge of this slam panel by a few millimeters to provide additional space for the do88 charge pipe.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFlexible hose connection in-between upper and lower charge pipes allowing movement which prevent the hose from popping off.\u003c\/li\u003e\n\u003cli\u003eSpecial designed 3-humped reduced silicone hose reinforced with high temperature rated aramid fabric and outer stainless-steel rings.\u003c\/li\u003e\n\u003cli\u003eSuper high quality hose clamps from Mikalor included.
