this is an extract of a K&N press release that is being used in the 4WD print press here in Australia. The full press release is here
quote:Note that nowhere in the article are any Silicon numbers quoted, either prior to, or after K&N elements were fitted. You would think that if the Si levels had dropped after the K&N elements were fitted, they would be crowing from the roof tops, but absolutely no mention anywhere. All those words and it doesn't really say a thing. Cynic, moi ?
Prior to departure, Mobil 1 engineers set us up with sample kits, and instructed us to mail oil samples back to Mobil 1 labs periodically. They also mentioned that the only thing likely to affect oil performance is high-silicate content from dust and contaminates. That prompted us to talk with ARB's Matt Frost (one of our sponsors) and a decision was made to fit an ARB raised air intake to our vehicles. But all of the dust encountered during the first three months of the expedition--especially in the aired planes of Patagonia--made it apparent that serious air filtration was needed. In Santiago, Chile we mailed oil samples to Mobil 1 labs and by the time we reached the end of the road in South America, the oil had changed to a darker color. We knew that something more than the snorkel was needed if the oil was going to make it. The decision to go with K&N came when we reached Australia and the locals told us about the bulldust along the Gun Barrel Highway, a 500-mile barren track--steeped with Aussie history--that stretches from east to west across Central Australia. The ground is made up of a bright-red dirt that the locals refer to as 'bulldust.' In no time at all, this fine, talc-like powder makes its way inside the vehicles and it gets absolutely everywhere." Fortunately the team installed the K&N Filters before running the Gun Barrel. "I heard about K&N so I sent a note asking for filters for our Land Rover Discoverys," said Baggarly. K&N arranged for four 33-2119 High Flow Air Filters to be sent by their distributor in New South Wales, Australia, Rocket Industries PTY, LTD. "They have been in our vehicles ever since--including the first all-land drive from Singapore to far Northeast Siberia. The World's Best Air Filter - K&N is truly the world's best.
