I'm not sure how it works, at first I thought 'fuel magnets' or 'eBay resistor' but then I remembered reading about this firm in a magazine, and realised I already swear by one of their products, Ecotek Power Boost engine de-coking formula. The first time I applied it to my JTD (105K) the effect afterwards felt unbelievable! Have applied it once since (120K) and it did make a little improvement, but nothing like the first time I applied it..
