Unfortunately those will probably continue to be a commodity item in the aftermarket, since the cost to design one from scratch and tooling for all the little internals is rather prohibitive. We did improve DME relay 99361522701 for '89-'98 911 with modern modular design however, and assemble it using Surface Mount Technology (SMT) for quality consistency and long-term reliability. See
this thread.

Thanks for the tip 911 Slant, we'll have our engineers do a review on those boots.
We use in-house FTIR (Fourier-transform Infrared Spectroscopy) analysis to compare the rubber in final products to what we specify (which is based on analysis of the OEM rubber), sometimes rubber suppliers will try to dilute the mixture slightly with a filler. Since "rubber" is a mixture of many things, it's a challenge to keep the final product consistent while keeping the price down, as everyone knows given the wide quality variations in the aftermarket vs money-is-no-object OE rubber.
We've actually just released some coolant pipe repair kits for BMW that include silicone hoses, because even the OE rubber hose sections are failing after only a few years. Hopefully the repair kits are successful and our use of silicone increases as we evaluate demanding applications.
