i have absolutely no idea if it will work or not... i've never heard of anyone making an intake for the 86-92 supra but i think you should email them just to confirm measurements etc that it will fit
also you can gauge by how long they take to answer and what their answer is like.. i.e short abrupt... not interested obviously, short polite contains all info you need... they're willing to have spent time to answer your questions
have a look and see if they have reviews on their site... has anyone else bought stuff from them?
just have a general look around about the company and really it's up to you to buy their product
if you do get it let us know how fitment went and also your impression of the company
