I have a 99' Isuzu Trooper S. I want to buy a cold air intake system for it but K&N doesn't make a system for my Isuzu. They only offer the rectangle filter for the factory installed one but mine is cracked so I have to do something and im thinking cold air.
in response to nathans answer - k&n intake systems require their own enviroment ( aka a box made of sheet metal that seals with rubber stripping. example - http://www.dragtimes.com/blog/wp-content/uploads/2008/06/63-1114.jpg so its NOT a Hot air intake.
Answer..... one of three things could have happend......they probally could not invent a system that would increase horsepower in your type of vehicle, maby because of engine size, location or avaible space. The stock intake has more than enough airflow and they just sell the filter to go from a good intake system to a great intake system or they figured that it would not be a proudct that alot of people would want to buy due to the low production numbers of theese vehicles. I found this on ebay if you are really set on getting an aftermarket intake system, its not a complete K&N system but its got the K&N cone filter you want and a short chrome tube http://cgi.ebay.com/ebaymotors/1999-Isuzu-Rodeo-Trooper-Amigo-3-2-V6-Air-intake-K-N_W0QQcmdZViewItemQQ_trksidZp3286Q2em20Q2el1116QQhashZitem370176232916QQitemZ370176232916QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories
