I'm weary of those kits for Boxsters.

I bought one for my car a long time ago and attempted to install it. The lamp itself was too long and there was a shield preventing it from fitting properly.

I ended up installing the kit in a Mazda 3 (also H7 lights). To this day they, surprisingly, still work, but just reading the instructions for installation should make you worry. They're written in broken/poorly translated English.

There's no splicing required with those kits usually.
