If you have to use the smaller inlet on the Eliminator, you can't use a k03x fitment TIP, it's about 4mm too small.
Use either an S3/LCR one - which I think will fit just fine - or use the piping that it comes with to fabricate your own.
Made up of a couple of 90 deg bends, which then would attach to an OE inlet. but you don't want an OE inlet, as the MAF will over read. (hence the need for an S3 MAF housing)
I think your best bet is to use their piping initially, then mod an S3/LCR Forge inlet to fit.
