We intend making plenums with 4 top mounted injector mounts and without all for Gen 2. The intercooled version will be somewhat different, we don't have a final design for that yet. We have idea's on mounting this type of plenum on the Gen1 but again its early days.
The fact that we are making the blow off valve integral to the design will save money and space over a seperate unit. SO a complete plenum with b/o valve and not requiring silicon hoses and clamps we are looking at around £670 with fuel rail. If you bought the fuel rail, b/o valve and plenum of this quality seperately it would work out considerably more. Without the fuel rail and a top half not machined for injectors we are looking at £590. Multiply by about 1.6 for USD. I think its value for money when you look at the quality and ease of fit.
