With a name like WRXHOON its no wonder you don't know what your talking about!!!!
To the person thinking of buying this for there R32 they have a hole so rather then taking any advice from these morons ring any good GTR workshop and ask them, then you will know and they might be able to help you with making a senser or welding up the hole.
WRXHOON stick with your elastic band WRX'S!!!
