Indeed, well i have done mine now. I bought the mocal one off ebay in the end for £75. And placed the filter in the front bumper running the hoses under the drivers headlight as this seemed the easiest route. The starlet thread size is 3/4 UNF.
Hahaa no problem, yeah i will take some tomz for you dude . I wanted to keep it as close and roughly the same height but in the end gave up and stuck it were ever it would fit (in the front bumper) ahaa.
