The point being that the oil cooler mod was hidden whereas the monster truck modified lists all the mods done in the article. Two totaly different situations and not comparable.

This also isn't a performance mod that stresses the engine. Even if the car isn't tracked the oil cooler is benificial not only in keeping the temperature reasonable in heavy traffic, etc but also by increasing the oil capacity which dilutes contamination in the system.

I suspect Nissan is concerned about extensive agressive use of the engine. Agressive use will result in safety mode and prevent extensive agressive use however with the oil cooler agressive use can continue indefinately and the results are unknown. This is a new motor again from the 3.5l and the VVEL is really unproven still so I can understand their concerns. Regardless if this inference is true the fact remains that they were dishonest buy not disclaiming the use of the oil cooler in media vehicles. It was only discovered by accident and IIRC it was hidden in the wheel wells... but dont quote me on that ;P
