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 delete kit for 1987-1997 Ford trucks and Broncos with EEC-IV ECUs :
** DOES NOT WORK WITH MAF **
These kits are designed for “off-road use” and will safely eliminate the SMOG, EGR, and un-needed vacuum sensors from the ECU.
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 delete kit for 1988-1997 Ford trucks and Bronco. This unit is essentially a switch that turns off the EGR and other un-needed sensor feedback to ECU. This allows the ECU and engine to operate flawlessly the way it should. In fact, it achieves better air fuel curves without the SMOG program operating. Additionally, our kit includes the belt to bypass the SMOG pump. With all of this combined you will make more horsepower, torque and allow the engine to get better gas mileage. Without our kit, if your truck has a sensor failure with any of these components, it will go into Ford’s EEC-IV “limp mode”, resulting in horrible gas mileage and a loss of power.
You can leave all of these components intact, or if you want to clean up your engine bay, you can remove them. If you need to go do emissions testing, simply remove the Twisted Smog Box and plug your system back in as normal. The other components only take about 10 minutes to swap back and go get emissions tested and be fully legal for “on-road use”. That being said, we always have passed tailpipe emissions even with the smog system eliminated.
** If you are planning on removing all of your SMOG tubing, purchase the SMOG pump tubing elimination hardware bundle option **
Included with this kit :
- Twisted Smog EGR eliminator
- EGR valve block off plate
- Serpentine belt needed to not turn the SMOG pump
- All connectors and mounting hardware
- Shipping + Handling Included
** Attention : If you don’t need a belt, or have a specific belt brand you want to run, you can purchase the “Twisted Smog Box Kit with no belt”, or that same kit with the additional elimination hardware labeled “Twisted Smog Box Kit plus Elimination Hardware with no belt” **
