How can I find a euro intake on eBay? I tried setting the filter but it comes up world wide. I much rather get one with injectors installed then drill it myself. Dapshop has the factory ones for cheap but the euro is enticing.

Try EURO ebay.uk/de websites and search for the ROW intake manifold part number 06L 133 201 AH. Not uncommon to find the intake manifold along with the fuel rail (06K 133 681 A) attached. I got mine off a Euro parts website called ProxyParts with the IM & fuel rail off a Clubsport with a few hundred miles for ~$180 shipped.

So you are using the factory rail? What plugs into it from our car if it didn’t come with this from the factory?

I haven't moved ahead with the install yet, but most people use an aftermarket harness from Precision Raceworks, CTS, or APR. You can buy the PR harness separately directly from the company, or from BMP Tuning.

Using the ROW MPI rail, you will also need to buy a fuel T as our HPFP only has one outlet. I bought this black anodized aluminum one (thanks for the link @vw671), good for e85 if you want it:

Hi guys
I’m thinking to upgrade my factory MPI injectors with Bosch injectors but heard than only PR injectors have correct spray pattern.
Is this true or only marketing??

The CTS injectors are just as good and do the job

Yup got my euro intake manifold from ebay uk. Was pretty cheap and made the mpi swap a breeze.

Do you think that this T connector will work correct? APR of CTS using connector with kind of bump on it!
Does anyone know what is this and where I can purchase it???

I’m sure it’d work great. APR or CTS won’t sell them individually though. And the one I linked works just fine for guys making a ton more power and boost than I plan to with that setup.

I have been looking for this part a while now. APR and CTS use it, they might not sell it separately, but it is also an OEM part for ROW. I just haven't been able to find the part# for it.

I am currently using the T connector mentioned above, but the OEM part would be a nice, cleaner look.

I’m looking on my engine bay with factory MPI and I can’t find this part:unsure::unsure:
Fuel line goes from left side of engine to HPFP and then from right side of HPFP to MPI rail.

Correct me if I'm wrong, but this T fitting doesn't exist for the ROW vehicles. The ROW HPFP has a separate fitting that supplies fuel to the port injection rail. Here's a link to a @littco post describing drilling out this fitting for improved flow to the MPI rail with larger than stock MPI injectors and tuning:


The ROW MPI rail routes fuel differently than the PR/CTS rails, hence the need for a T when using the ROW MPI rail with the single outlet NAR HPFP.
