So I'm looking at uprating the air intake for my 4.2 .. I've heard whispers of a guy who makes them on this forum? I'm in the Uk if it makes a difference, also can people list pros and cons?

 

When I bought mine I found it already had k&n' filters fitted.

So purchased a new set and had them changed out in my 2019 service, cleaned and reoiled to old ones amd am set to go in 2021.

What exactly are you looking for a ramair type of arrangement?

 

What makes you think that the factory intake isn't good enough?

Read this old tread from 2012.

There's a reason you won't find an aftermarket CAI for our XKRs. The factory design is as good as it gets for street performance. Forum member jahummer can tell you about his race car's setup.

 

Here's his thread from 2018. It's worth reading even if you're not going to race your car.

There can be benefits from changing the intakes, reduced weight, increased supercharger whine, better air flow and increased performance. The later two however require other changes such as a custom exhaust that helps with flow and adjustments to the ECU map to account for changes in VE, etc. Wouldn't hurt to increase throttle body diameter, port supercharger, intake manifold, etc. You may ask Chris at Mina Gallery if he ever finished the dual intakes he was working on and I believe Eventuri had an expensive carbon fibre option.

What's the bang for the buck? Sure, there are power gains to be had, but whether it's worth the cost depends on your needs and priorities.

For me, stock is fine since I don't track my XKR. I'd rather put that money towards fine dining at restaurants with my wife and vacation travel ... when it's safe to do so.

 

Take a look at my thread. I have been using this setup for a while. More filtering area, more flow possible, same great oem paper filtration vs kn types.
But if your looking for performance bang for buck, it's definitely in proper ECU tune, nothing else comes even close

Thanks Alex, I've seen you about on the forum for a while too, I'm booked in for a map in the new year. Pretty much everything else in place but was showing stock bhp figures at the dyno so hoping for some improvements..

 

I can do remap for you feel free to pm me to discuss

 

done

 

Thanks, looks to only be for the 5ltr otherwise I would have done a buy!

 

An intake on the XK is a big waste of money IMO. Jaguar got the deisgn right, from the start. K&N filters are not an improvement. Tune and throttle body customizations are neat idea. I believe the racing XK's still utilize the factory style intake, no?

 

They do not use the stock intakes. Have a look at the Apex, RSR, Emil Frey, etc. they all have massive custom intakes along with re-bored blocks, enlarged manifolds, larger exhaust, etc.

 

As others have stated, the throttle body and intake elbow are more of a restriction than those intakes.

 

Is it different placement of the air filters locations on the car?

 

The key to an air intake is that it takes in air that is as cold as possible- the jaguar intake is ideal for this- low to the ground, away from aerodynamic deflection, and away from the heat of the engine. Colder air is more dense and will give better performance than if the air intake is drawing in warm air. If remapping or modifying K and N filters in the original intake are great, but in a standard car the standard filter will not be restrictive to engine performance as long as its clean.

 

Actually the Jaguar location is in front of the radiator pointing straight up at the top of the nose cone. My custom ones are pointed forward and located in the bumper cover side vents taking in air from the lower grille and side ducts.

 

 

Is there really that much clearance between the S/C and hood for a 2-3" pipe like that?

 

Neither of the racing intakes look viable for a production car; too home made looking. Fine for racing or those who want to modify their car.
