We have seen from doing some customer research, that most people who go about installing their own hydrogen conversion kits via one of the DIY guides below , find it to be relatively painless and rather straight forward. Having said this, most of these people had a basic understanding of how to do scheduled maintenance on their car, and so it was nothing too big of a learning curve for them.We suggest that if you are not very handy with making some simple checks and changes under the bonnet of your car that you think about getting the guide and having a qualified mechanic put it in for you. If you purchase the guide, you can then print it out and simply give your mechanic instructions to follow the guide, and this will insure that someone who knows what they are doing, can install the kit for you.
