What size MAF sensor do I have

[nuggets]

Its metal and the plastic piece on top has f17f-12b579-aa-afh55-03b stamped on it. Thanks for any help.

Pull the duct off and measure the opening at its smallest part. There are approximatley 25 MM to an inch

25.4mm = 1 inch.

A stock MAF is 55mm or just over 2" in diameter.

Thanks for the info. It is a 55mm. With the mods in my profile would a bigger one be a good investment?

with heads and a cam it would be a great investment. cant believe youve done so many mods and still kept the stock maf. what size is your tb? you didnt mention. if thats stock, get a larger one

I'm guessing my tb is stock too, as for the mods I bought the car with them already done. what size maf and tb combo would you guys recommend?

It will really depend on what your future plans are for the car... Forced incuction or spray, you might want to hold off on getting parts until you know what you are going to buy / or have.

For my car I would like to have a 73mm or 77mm MAF and a 65mm TB. Getting more air into the engine means that you will make more HP.
