Will a cold air intake for a 2005 Toyota 4Runner.

Not all cold air intakes universal. Maybe the filter at the end of the intake universal but the piping is usualy vehical specific and I think that your engine being the same and I believe everything set up the same in the engine compartment it should be simple enough. As long as you have a place for mass air flow sensor you good to go. Make sure you clean and oil it properly or don't bother with it. Just stick to the factory unit if you don't want to spend the time because you can da. Age your engine if not taken care of and get lower your gas mileage
