NWP Engineering 75mm Big Bore Throttle Body Adapter Plate Kit - NO 75mm THROTTLE BODY UNIT or ADAPTER WIRE HARNESS INCLUDED

If you need the 75mm Throttle Body or Adapter Wiring Harness, it's best to purchase the full kit HERE since our Throttle Body Unit is calibrated and guaranteed to fit and perform flawlessly with all types of intake manifolds and vehicles; unlike using a throttle body unit found at the parts store or salvage yard. No modification required! Refer to our 'Vehicles' Tab for applications.  Also, our Wiring Harness is designed and built to the same standards as the OEM engine control harnesses in your Nissan.  This is a very reliable and race proven harness!

Upgrade your throttle body from 70mm to 75mm!

100% Plug and Play. No tuning required!

Our patented Adapter Plate design fits both RWD and FWD VQ35DE platforms flawlessly!

Features a tapered and port matched bore for the smoothest airflow and most power!

Do you have our 5pc Maxima/Altima Phenolic Spacer Kit or our 4pc 350z/G35 Phenolic Spacer Kit?
If so, you will want to answer "Yes" to the question above to receive the longer bolts.  The Phenolic Throttle Body Spacer you have is a 1/4 inch thick and will go between the aluminum 75mm Throttle Body Adapter Plate and your intake plenum.  Everything is perfectly port matched for the smoothest airflow and highest HP gains!

What people are saying:

The reason I give you guys so much support is because you make a quality legit product that you stand behind, offer impeccable customer support, and basically do everything (both business wise and technically) that I approve of, and would do myself, if in the same shoes. You are running a helluva outfit over there NWP. Keep it up! - Jake from Lubbock, TX

When I received the package from NWP I was thoroughly impressed with the quality of the adapter piece. Install was simple. Definitely a DIY job with basic hand tools. Throttle response is fast and crisp. The butt dyno says that it is making power in the upper RPMs, and did not feel any noticeable loss down low. It seems to be really pulling in the 5K+ rpm which is consistent with the dyno charts that I have seen from NWP. I am impressed with the upgrade and think is a very good bang for your buck that will compliment most other bolt on mods on the market. - Danny from Slammered-Inc (aka GreenGoblin - Turbocharged G35)
