wow, even I know how to use a search button. but since this is your third post............. today on the exact same thing, you need to do some research on your own.

Im not trying to be mean but if you search and still can't find anything then come back and ask for help

it is the white tab button on the top of your screen that says, " search " just between "new posts" and "quick links"

check it out. it will help a ton.

4 threads for the same question? I don't THINK so. 1 thread per question in the future.

First. Any lexus that uses the 4.0 litre V8 and a karmen vortex AFM like ours will do. There were quite a few of these. I'm relatively certain that you can take the one you have to a local junkyard and look for another one that looks the same.

Second. The MAFT really is a better solution, it's worth it to read the manual, read the posts on how to install it, read the install guide posted here in the Tips / tricks section, read on the Full Throttle Motorsports forums, digest some of that, and install it.

Third. I hope you really do have the 550cc injectors to go with this. And that they are installed. Normally I'd assume that this was the case, but when faced with spelling, grammar, and online manners like this, I have doubts.

fyi... follow what grim just told you.. if you don't have the 550's already installed you will run lean with that lexus afm... running lean is bad..

Do you need 550cc injectors? I heard 440s are perfect because Lexus v8 maf creates 25% more air intake and 440cc injectors are 25% more fuel intake than stock 330s. If you were to put in 550s you'd NEED a fpr and safc?..

550s are mandatory - as is a fuel pressure regulator that can feed the injectors. Stock FPR doesn't have a high enough pressure. Oh, and the ideally a walbro to go with it.
