Custom intake on a 4AF - Toyota Nation Forum : Toyota Car and Truck Forums

I did a search and didn't really find what I wanted for this so I was just wondering, what can I do for a custom intake on my 4AF or is there an aftermarket one I would be able to buy. What would you suggest for an intake. How much of a horsepower/torque gain would I get from a great big cone filter? Any ideas would be great also I had seen that Flashmn had made a custom one what exactly did you do to make it? Thanks in advance.

None really. There isnt really any use doing a custom intake if you plan to use the stock carb, its a very limiting factor.

Depends.. is it a 4AF (carburated) or a 4AFE (fuel injected)

There's not much you can do with a 4AF other than getting the K&N Carb filter.

With a 4AFE, I believe the intake for certain Civics will fit, I think you just have to block the hole for the hose on the side of the intake. Ask Xenon, he did it with his 4AFE and he could tell you exactly which intake will fit the 4AFE.

I was just kinda wondering, are there any carbs that would increase performance but aren't as expensive as the weber that would work?
