Our modified TB's give back much better throttle response and a noticeable power gain across the whole driving range with an extra punch at wide open due to the smoother and extra volume of air it delivers. Our modified TB's are unique as we have reworked them extensively giving you more features than the competition. They are optimized for maximum gains. For the money spent this is one of the simplest and most cost-effective mods you can make. Our TB's work excellent on stock to modified vehicles. They are an excellent value and performance improvement.

IDENTIFYING YOUR TB:

  • The TB's can be identified by using the last 3 numerals of their part number.
  • The TB started with the part number "805" and was used for the first two years of 2003 and 2004.
  • In 2005 the TB's electrical connector end was changed to a slotted connector and a new casting was also introduced.
  • The 2005-to-2012-part numbers are the "801" TB and "847" TB.
  • The "805" and "801" are identical except for the electrical connector. The "847" is a different casting and uses the slotted connecter.
  • All the 2013 and newer vehicles use the "251".

    Compare your TB to the pictures below to properly identify which TB you have.

    OVERSIZED Custom Ported TB FEATURES:

    This is a Fully Oversized reworked Factory TB. For those of you that require more air than our Standard Modified TB can deliver we Large Opening Custom Ported Throttle Body.

    With a Maximum Custom Ported Bore and matching Oversized Blade plus the 4mm Half Shaft these are the biggest and the highest flowing factory modified TB's made. No other competitor's factory modified TB outflows this one. It takes some effort to build these as they are much more labor intensive than our Standard TB's we sell. The price is set accordingly.

    The specifics of the Custom Ported TB's are as follows:

  • Front Side Taper Boring: The opening of the TB is Radiused and Taper Bored.
  • New Custom Blade with the correct factory angles
  • Half Shaft: Modified Factory Shaft. The top of the shaft is removed providing more airflow at wide open throttle.
