I would be glad to pay all shipping/handling charges. For background my car has been eating a lot of oil 400-500 per 1qt so I am doing multiple consumption tests with the dealer. After 3 months of tests they changed my sparkplugs and oil consumption is still at the same high level (how surprising!!!) I think they are getting ready to take action but my car has a K&N filter (otherwise 100% stock) so I just dont want them to give me any grief about it. Before you respond and say that an aftermarket airbox has nothing to do with oil consumption please keep in mind I am dealing with a dealer and a car company that previously said that fouled sparkplugs could be linked to oil consumption....Thanks!
