Due to the popularity of this product, we are now able to offer an improved price!

High flow performance exhaust manifold, stud kit and gasket package for all Td5 Land Rovers.

Improved gas flow reduces irregular hot spots, reduces turbo lag and eliminates manifold warping.

Ideal for tuned vehicles, also benefits standard tuning and improves throttle response.

12mm thick cast flanges for super strength.

NOTE – This is not a modified standard manifold which will warp again even once skimmed and the webs removed!

Available with ceramic coating in various colours

These longer studs are supplied with stainless steel expansion spacers to help eliminate studs breaking off in the cylinder head due to manifold warping. Supplied with new flange nuts, the longer studs are rolled rather than thread cut and made from stronger material.

Compliments our performance exhaust manifold

Kit supplied with 3 gaskets – manifold to head – manifold to turbo and turbo to exhaust downpipe

*Manifold cast in France.

    Very good quality cast manifold upgrade for my TD5. Since it’s cast, My advice to anyone getting this is to spend a little more money and have it ceramic coated to stop it going brown, prevent any potential hot spots and to keep the heat down in the engine bay.

    • AlliSport Web

      We appreciate your feedback. We will investigate this further with some back to back tests and collate data to see how effective this process is.

    Great product and wonderful fitment. Only issue I’ve found in having this fitted is accessing the spinner come service time becomes a “turbo off” job as the different manifold shape prevents you from getting the spinner lid out. Still well worth it in my opinion though

    • AlliSport Web

      Thank you for your review and feedback and we’re really glad that you like our product! The Spinner should be able to be accessed although it can be tight.

    Great product , hasn’t warped even under heavy heavy loads and travelling thousands of miles in the desert and mountains at 50° celsius , only slight bummer is the rotorfilter is slightly more difficult to access .

  5. Kris Chorley (verified owner)

    Great bit of kit. No blowing and really can feel the difference in my defender!

  6. Magnus Andersson (verified owner)

    Manifold is a great piece of craftsmanship. Easy to fit. Did have som trouble with the lower front stud, it was impossible to use any tool to fasten the nut due to space. I ended up not using the longer stud and extra expansion spacer since there simply wasn’t room to fit it.

      Thank you for the feedback, the front lower stud can be tight. Often the studs are not quite straight in the head which can make them tighter.
