The air filter is very Ok.K&N is a reliable manufacturer. However delivery was very long as the filter was not in stock. It came from a british subsiduary. I hope this product will not be discontinued by K&N. Regards.

There are a lot of us out here running 89 series Land Cruiser with the 4.5 liter engine looking for a good air intake system to give us a little more power. The filter above helped a little but a kit such as the one you make for the V8s would be a lot better. Please consider such a kit for the inline 6 4.5 liter engines in the '96 & '97 trucks.

1st filter was damaged during shipping. Notified customer service and they reshipped with next day delivery. Fine product with excellent customer service, what's not to like. Will definitely be a repeat customer. Thanks
