We are proud to offer the only performance upgrade intake for 1988-1997 460’s. Whether you have built up your 460 or wanting more out of your stock motor letting it breath is always the answer to more horsepower and torque. Having seen the drastic performance increase with ported and balanced single plane manifolds paired with multi-port efi we had to give it a shot. The result was an instant and undeniably increase in power. Starting with Ford’s factory intake we start by cutting the stair-stepped bottom out. From there we remove all the internal passages. They are cut back into a balanced much short length. The air no longer has to get drawn through long runners that make sharp 90 degree turns. Instead each cylinder can now easily draw the air it needs to make the power a 460 is capable of. The easiest way to describe the difference is, instead of downshifting just lay into the throttle and watch the speedo climb. As always, we did 12 time trial pulls before and after the intake. The difference was 1.75 seconds difference in 0-60 in the pictured blue and white 9000 lb. Monster. Everyone who has gone for a ride has said they all felt a huge difference. As the driver it feels like I just unhooked the flatbed trailer.
Depending on how quickly you need your new intake, there are two purchasing options:
Option 1: We don’t charge a core charge. You send us your intake for this service, and we verify that it’s usable. If it is, we send your new intake out the same day. Price includes S+H on delivery of your new intake.
Option 2: If you need your new intake faster, pre-pay the refundable core charge of $125. We will immediately ship your performance modified intake, simply send us your old one. Once we receive your intake in usable condition we refund the core charge fee.
An EGR Diagnostic Isolator for 1988-1997 Ford trucks and Broncos with EEC-IV ECUs :
We are currently take pre-orders for the Twisted Smog Diagnostic Isolator. We are waiting on labels for the new product, and anticipate that we will be able to ship orders no later than the 20th of January.
** DOES NOT WORK WITH MASS AIR FLOW (MAF), FOR EEC-IV ECUs ONLY! **
These diagnostic isolators are designed to temporarily separate the SMOG, EGR, and corresponding vacuum sensors from the ECU so you can easily isolate a sensor issue.
If your EGR system is suffering from a sensor or component failure, your truck will run in the EEC-IV “limp mode” – resulting in horrible gas mileage or your truck running dangerously lean. This isolation tool will allow it to run without the SMOG and EGR temporarily, without going into the “limp mode”, so you can then safely isolate and identify where the problem is coming from. This will allow your ECU to run the engine solely off of the needed fuel injection sensors and components. This is for temporary use, and cannot be “installed” permanently in your vehicle.
Using the same approach as we take in our vintage stand-alone harnesses we are now able to do a full EGR, vacuum sensor and smog system isolation for 1988-1997 Ford trucks and Broncos. This unit isolates and partitions off the EGR sensors and components in a way that allows your engine to only run on the needed fuel-injection components. This allows the ECU and engine to operate temporarily without the EGR and SMOG components. Additionally, our tool kit includes the belt to bypass the SMOG pump allowing you to diagnose if the problem is coming from the SMOG pump itself.
You can then easily reconnect your vehicle for SMOG compliance.
** If you are needing to on isolate all of your SMOG tubing, purchase the SMOG pump tubing isolation hardware bundle option **
** Before you Buy : It is highly recommended that you fully read the instruction manual fully prior to purchasing to understand what this tool does, why it does it, and what the scope of the project is beforehand. **
Included with this kit :
- Twisted Smog Diagnostic Isolator
- EGR valve block off plate
- Serpentine belt needed to not turn the SMOG pump
- All connectors and mounting hardware
- Shipping + Handling Included
** Attention : If testing the SMOG pump itself is not needed, you can purchase the diagnostic tool without the belt. **
