K04 Charge pipe to replace the L shaped pipe and red elbow which comes as standard on all BAM and AMK 210/225 bhp engined cars.
We designed the first version of these back in 2013. Since then, due to advances in machinery, we've re-worked it so we can make it from one continuous length of cnc mandrel bent pipe. We've also moved the spurs for the diverter valve and boost control (N75) closer to where they need to be, helping to tidy your engine bay even futher.
Our charge pipe meets up with the turbo and does away with the red elbow (the one which frequently melts). It's made from larger diameter 63.5mm OD pipe (standard charge pipe and all other aftermarket charge pipes are 60MM OD) and has no baffles (the one's which people try to remove from the standard pipe). It doesn't have the large step inside the pipe, where the internal baffle would be on other pipes. It has a much smoother, longer bend in the middle and doesn't have the large dent on the underside (the dent that the standard pipe has for clearance over the cam-belt cover). To sum it up, we've removed all restrictions and made it more reliable.
We've recently given you more options for ordering. You can now buy the unfinished version, which is ideal if want to paint it or maybe even polish your own? There's a crazy amount of effort that goes into finishing these, so it almost broke our hearts when we saw that some people were painting/powder coating them! Now you can save us the hassle and save yourself £40 in the process

Nomex lined N75 and Diverter valve (if applicable) hoses in black, red or blue.
Fitting is quite straight forward, however you will need to trim the rear cradle to allow clearance for the longer, smoother bend (see images above). The biggest query we receive about the fitting of this charge pipe is, whether or not to re-fit the rear bracket/cradle or leave it off. Our response is this; We always advise fitment of the rear bracket and clamp, as it makes it impossible for the pipe to move around, which in turn helps prevent boost leaks at the turbo end. If the rear bracket isn't used, the coupler now has two jobs, instead of one, the job of holding the charge pipe in position as well as the job of being a gas seal. Ultimately, the decision is yours.
*Additional Info* The operating temperature for the manifold and turbo is between 850 and 950 deg C. The working temperature of the Nomex liner on the coupler maxes out at around 250 deg C and the outer polyester layer maxes out at around 180 deg C. Using this information, it's clear that you'll need to shield your charge pipe and especially the coupler, from the radiant heat of the manifold. Just how far you should go with heat shielding very much depends on your setup, power output and use.
This is classed as a supporting modification and as with all supporting mods, it's all about the package, rather than the single item, so performance gains will vary, however reliability will be improved in all cases.
