picture of my new range rover intake installed.....notice more zip already ...thanks avos for the suggestion

Come on brother..

Can you share a link to get one of these sexy things?

of course ...goggle or search ebay for this part number

(4H33-9C684-AC).....it is the ribbed pipe going from throttle body to 90 degree shiny elbow

A caldoofy or mina gallery pipe, or the like will be needed also ....the rubber hoses are a 4x3 and a 3.5x3....the throttle body hose stays the same

Check a website called gentlemenofsalvage....breakers in the UK

Hi
What the difference, they look identical apart from the ribs on top
are they larger bore
many thanks

Larger inlet and internally....better flow at throttle body....

The rear part on the stock one is realy inefficient whereas the RR one is better designed there and offers more flow onto the TB, that next for being a bit larger in diameter which helps as well.

For info, the full intake setup of the Ranger Rover was larger as well, they included even a 90mm MAF.

nice bit of info .

wouldn't a 4'' alloy pipe with a silicone elbow be an improvement even over the RR intake ?

4" is really to wide for the airflow on these setups, 3.5 is already on the big side, so if you could make with that size a smooth turn with large radius, than that would be best.

In the RR intake itself is also a bell shape at the rear, and my best guess is that the RR one is already close to what you can achieve for maximum flow on these setups (so at max a pulley change).

Thanks for the suggestion. I already have a Caldoofy intake. On a whim I went on ebay. Made an offer and scored. Even comes with the rubber and clamps to connect to the TB.

Happy Holidays everyone!

That's great ...you will like it....just have to remove a little of the ribs under the metal xover bar and done....real easy to see when you fit it

hi
can the range rover maf be fitted to the s-type r
would that help improve flow
thanks

One last thing....for a better fit, i used my vise with soft jaws to squeeze the 90 degree shiny tube into an oval shape to make the connection better at the rubber hose connecting to the new intake

joe....looks like the range rover maf is a separate unit, whereas the str is made into the airbox lid....also I believe oem RR is bosch, looking at a used one on the breakers website...if you could fit the RR maf in, then you would be able to use a 4 inch connecting tube i would think....avos has his twin-screw setup larger , but he knows what he is doing, so my advice is just conjecture if you know what i mean

I already have the Caldoofy intake fitted, will I still need both of the extra hoses that you list ?

Sorry to be stupid but do you mean 1x hose of 4 inch diameter which reduces to 3 inch diameter and another 1x hose 3.5 inch diameter reducing to 3 inch diameter ?

Never stupid, not to me anyway.....glad to help.....i believe the caldoofy tube is 3.5 inches matching the airbox outlet.....if so, you would only need a 4 to 3.5 inch rubber reducer hose....easily found on many sites.....i have the mina tube that is 3 inch.....that is why mine is 4 to 3.....the new rubber intake hose connects to the new Range Rover intake ....a little custom cutting of the ribs on the intake for clearance, a little squish of the tube to make it oval, and good hose clamps at all connections and you are done

Thank you for taking the time to reply Scott (and a Merry Christmas !)

hi
also worth mentioning, the Caldoofy intake comes in two sizes
he does it in 80mm for the STR's and 90mm for the range rovers
the 90mm has to be the better option, as he is selling both sizes through ebay

Thanks Joe, did not know that.....might upgrade to the caldoofy pipe.....first i am going to the first stage blower pulley and see how that works

Question to OP or anyone, did the STR come with ribbed charge coolers in the later years or did you swap those also? I ask since I was going to swap to the STR coolers for the 'SUpercharged' inscription, they did away with that on the XF while it still had the 4.2 motor.

Is there any difference between them? I run it without the plastic cover and the old coolers would complement the engine more. Thinking of doing the swap when supercharger rebuild comes due. Thanks.
