The 4 door Jeep also known as JK was first produced as a 2007 model year. Jeep never produced a four door Wrangler. All Wranglers have two doors. Jeep did introduce the four door Jeep Wrangler Unlimited back in 2007.
One of the most enjoyable Jeeps to work with today is the Jeep YJ Wrangler, as built from 1987 to 1995. The generous YJ engine bay allows for a comfortable, clean fit for GM Small Block V6, V8 and even Big Block V8 engines.
