I have a non-US 1970 FJ55 Toyota Land Cruiser in Costa Rica. After several mods to it I had to return the stock number you had listed for it..in return I gambled for the e-2440 diesel listed one. A very good chouce..it was a good fit..the engine power and torque increased..in short...a great result, awesome bang for the buck.. I am very satisfied with the product...I've been using mostly K&N filters on 90% of the time on my vehicles...to me this was an obvious choice...but the engine response I got this time was far greater than I expected. Good Job guys Awesome product!

Great product, more airflow than stock, eco friendly, and I notice improvements in both performance and my fuel usage. I recommend a K&N filter for all vehicles.

The filter arrived home with no problems and was a perfect fit. I could feel instantly a difference in performance in the old 4.5 liter Land Cruiser engine. I would strongly recommend K&N both for the products ans purchase experience.

Easy, correct price, on time shipping. Plus an easy to negotiate web site. The online experience is the same quality as the filters we run in 3 different vehicles.

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.
