Hey All,
As some of you have noticed, we have discontinued our TBI (Throttlebody Injection) kits for the N54 and N55 platform. We’ve been getting quite a few inquiries about that so we thought we address those here.
Why were they discontinued?
The majority of TBI users were budget conscious so with the introduction of our new DIY port injection kits and the low price point on those, it no longer made sense to offer the TBI kits as well.
What are the benefits of running port injection instead of TBI?
Six individual injectors instead of two nozzles
Injectors are PWM controlled
One injector per cylinder
Plug and play integration
More versatility for future upgrades
Compatible with all fuels
No Hobb's switch required
Can I still purchase just a throttle body spacer?
Yes, those are located here:
Throttlebody spacer
Can I purchase nozzles, injectors, fittings, or fuel lines for the spacer?
No, we no longer carry any accessories for the throttle body spacers.
I have purchased one of your TBI kits, what are my options to upgrade?
If you are the original purchaser, you can purchase one of our Bronze, Silver, Gold, or Platinum port injection kits and we will give you a $150 discount code to use on our website toward that purchase.
In addition, if you purchased an ethanol sensor with your TBI kit, we can integrate that as well at a reduced cost.
