Ordering this with other parts?
If your cart mixes direct-ship parts with items we hold locally, checkout combines them into one delivery charge and picks the cheapest service for each automatically.
To see and choose from the full list of delivery services, we recommend ordering direct-ship parts on their own.

Direct shipped from our US warehouse
What Is Direct Shipping?
This part ships straight to you from our US warehouse rather than sitting on our shelf in Clyde. You get a wider range and current pricing — the trade-off is that it takes a little longer to arrive than something we stock locally.
-
You Order
Check out as normal and you will get an order confirmation straight away.
-
We Place The Order
We order the part the same business day and it is picked from our US warehouse, brand new and factory sealed.
-
It Ships To You
It flies direct to your door by courier — it does not route through our workshop. You get the tracking number as soon as it leaves.
-
It Arrives
If you ordered anything we stock locally, that ships separately from Clyde — so an order can arrive in more than one delivery.
Delivery Time
Our supplier quotes 2–4 weeks from order to delivery.
No Import Fees
This part ships to you from inside the United States, so there is no customs clearance, no import duty and no brokerage fee.
Any applicable sales tax is calculated at checkout.
Product details
Injen's SP kit replaces the factory airbox on the 2.4 GDI with mandrel-bent aluminium tube and a washable cone filter behind a heat shield. The MR Technology tag means the tube diameter and bend are set so the factory MAF still reads correctly - it is a bolt-in, no tune needed, no check engine light.
- Mandrel-bent aluminium tubing, black powder-coat or polished
- Washable cone filter and heat shield included
- Uses the factory mounting points
Straight answer on a naturally aspirated 2.4: a couple of kW and a much harder induction note. It is a sound and servicing upgrade more than a power one. If you want numbers out of a YF or TF 2.4, this is not where they come from.
Good to know
