WORLDWIDE PCT PATENTS PENDING
PROTECTED BY CHINA UTILITY MODEL PATENTS; CN206054094U & 206129406
Choose Your Sound: With the removable extended trumpet, you can configure the T9401 to give you either a classic “whoosh”, or the loudest, most unique whistle sound you’ve ever heard on a Euro vehicle!
Customise Your Sound: The T9401 also features adjustable spring pre-load so you can fine tune when it blows off, and for how long. A softer pre-load allows the valve to blow off for longer and at lower engine loads. If you prefer to hear it only at higher engine loads you can use a firmer pre-load.
Low-Profile, Easy Installation: Using our integrated solenoid design stacked in an “over/under” configuration, the super-low profile allows clean and simple fitment (even if your aftermarket intake is using up all the space!)
If you haven’t already checked that your vehicle is on the fitment list, do that first using our vehicle search function above.
If you get a few different valve options for your vehicle, use the guide below to make sure you’re choosing the right one for your needs:

We live in a throw-away society, conditioned by cheap products and frequently released new models, to expect eventual failure and discard something when it stops working or is superseded. However, pride in workmanship and our commitment to quality means that when we put our name to something, we are also staking our reputation on it.
That’s why we back our products with the best Warranty in the business! You should expect a lifetime of use from a well-engineered product, so if your GFB product fails as a result of defective materials or faulty workmanship whilst you remain the original owner, we will repair or replace it. For full warranty details, please visit the GFB Australia website.
If the fault of occurred as a result of usage outside of the terms of the warranty, or you are not the original owner, fear not, we can still help you. You should never need to throw a GFB product away, as spare parts are available and won’t cost the earth.
Tech Support: We don't have a "Tech Support" team or department. We have engineers. When you contact us through our tech support email, you will be dealing directly with the engineers who actually design GFB products. They have more experience with the product than anyone on the planet to ensure you get the right advice.

Do you ship aboard (outside the UK)?

For all customers outside of the UK, the prices on this website will have 20% UK VAT Tax removed at the point of checkout (once you've entered your billing and shipping addresses). However you will likely have to pay some form of Duties / VAT prior to delivery of your goods. You are responsible for paying those charges. Failure to do so will result in the goods being returned to us. As the shipper, we will be charged again by the carrier to return the goods. This amount will be deducted from any refund you may be due.
If you are unsure of the customs and duty charges, we recommend you should contact your local authorities ahead of placing your order.
We do our best to ensure our stock data is accurate on our website. If we're ordering parts to fulfil your order from other manufacturers or suppliers, there can be delays in them despatching goods which may affect the overall delivery time. We will endeavour to do our best to keep you informed if things don't go to plan. We estimate the likely despatch times when you're looking at each part number. If you require parts urgently, please call us on +44 (0)1823 690281 before ordering to confirm availability.
Thank you for purchasing products from Octane Distribution Ltd. We endeavour to offer the best quality products and aftersales care but if you do find yourself in the position where you would like to return goods, we are here to help.
We try our best to ensure correct product/vehicle listings but there are always exceptions to the rule and no cataloguing is 100% accurate. The best advice we can give is to visually check to see if any parts you have ordered fit BEFORE disassembling your vehicle. If you are unsure, please contact us for advice.
Products Incorrect / Damaged / Faulty
You must inform us of any damage or shortages within three working days of receipt. If items are missing from your order, it's most likely that they are on backorder and will be despatched when in stock. We are always happy to clarify this if you get in touch.
Products No Longer Required / Ordered by Mistake
You have 30 days to return unwanted items that are unused and in their original condition (including any packaging, tags and labels) with proof of purchase (i.e. a receipt or order confirmation email). Some exceptions may apply. You must always check with us first BEFORE returning the items and we will give you a returns number to help us with processing and identification. Items returned may be subjected to a restocking fee if the goods are damaged or show signs of having been used. You will be responsible for paying your own shipping costs for returning the items. Shipping costs are non-refundable and we would recommend using a tracked/insured courier service and we accept no liability for orders returned with no proof of delivery.
If you have any questions about returning goods, please contact us.
