That intercooler has to go in the front bumper. If you put it on top, you will have to get a Carlos Sains top hood.
It won't fit on top of the engine, unless you get a smaller one. Besides, its more effective up front. But you will need to place a mesh in front of it. One thing, its a small intercooler. In this case, the bigger the better some what applies.
The exhaust looks ok. These kits are universal kits and on the list of cars. I didn't see the RAV4. Which means, once you buy it, your on your own for purposes of the seller. Would I buy it? No. Sometimes our eagerness to have power gets the best of us when it's time to buy. That is just some advice. When your 54, these things have happen to me already :wink: But hay, if you are interested and have the money and the know how, tools and place. You would be a first in our forum.
