  1. Ben

    Great quality intercooler! Would recommend.

  2. Mark Rivron (verified owner)

    Does exactly what they said it would. A notable increase in torque and a lot more free revving. The vehicle is a 1997 90 tdi with 250000 miles.

  3. Bart Voordeckers (verified owner)

    Just finished installing this full size intercooler on my Defender 90 300tdi.
    What a difference this makes!!!
    Worth every penny.

    Absolutely stunning quality from Allisport. Superb customer service and fast delivery times. The intercooler has made a huge difference to my D90. I’ve since bought other products from Allisport. Spot on. Thank you.

    GREAT PRODUCT!!! I was able to instal it without too much trouble. I am new to mechanic work too. I did have to drill two small holes in the slam plate and fold over the lower tab on the painted trim piece around the radiator. Other than that it was easy. The lower hose was just slightly too short and leaks just a little bit. Allisport put a longer one in the mail to me right away. Even with the small boost leak, the improved performance was very noticeable!! The turbo spins up way quicker and seems to give better boost although I haven’t measured it. I highly recommend this product. It literally breathed new life into my old 300 tdi.

    I purchased the 300tdi Full Size Intercooler from Allisport prior to leaving on my 17 solo road trip to Baja Mexico. My 300tdi had been previously tuned and a VNT had been installed but I had been having issues with the engine overheating prior to ordering the Allisport products. I installed the Full Width Intercooler along with the XL Allisport Radiator and the Radiator Frame and then went on my way to drive 4400 (US) flawless miles to all of the remote corners of Baja without any overheating issues whatsoever. I can on occasion be a difficult customer because I have worked in the product development industry for over 20 years now so I have much higher standards when it comes to quality and level of detail than the average person. The Allisport product quality is absolute perfection and their customer service is terrific. I can’t say enough good things about Andrew, his crew and the products that they make!
