2016-2021 Civic 1.5L Turbo Inlet Pipe

This is how you REDEFINE the Aftermarket; Huge cross-sectional area increase, retention of all OEM controls, one-piece construction, and a visual boost that will be breaking necks at every show. _{*prototype pipe shown}

On an OEM Turbocharger setup the gains from the install of the 27WON Turbo Inlet Pipe (TIP) are small. This is because the factory equipped turbo is so tiny and undersized, it's the bigger flow restriction. Testing across multiple SI trim Civic's showed us an average net gain of 2.2hp and 3.4wtq. These numbers are slightly higher on Base trim models that come from the factory with a much smaller plastic turbo inlet pipe.

It was not until we equipped our CivicX with a W1 turbo drop-in upgrade that the TIP really started to shine in the performance category. The addition of our TIP (aka cross-over pipe) to the larger aftermarket turbo kit netted us over 17 g/s of flow which is huge for such a simple bolt-on part. With the addition of the TIP, we saw horsepower gains of around 9hp.
_{***Note*** While a tune is not required we recommend one for optimal performance.}

The 27WON Turbo Inlet Pipe works especially well with our 80mm RACE MAF for both SI and non-SI options. You can get this 3.14" sized MAF housing as an upgrade to your existing 27WON intake or buy it brand new with full intake systems.

• Some metal tubes need to be bent slightly during installation of the turbo inlet pipe. _{Click for image of pipes location before. Click for image of pipes location after moving them.}
• The wiring harness cover for the turbo wastegate actuator will need to be removed and replaced with the provided shrink wrap.
• All TIP's are hand crafted and as such some variation exists between each and every unit.

The 27WON Turbo Inlet Pipe increases the inside diameter to 76mm, a 42% increase in cross-sectional area. This drastically improves the efficiency of the intake system resulting in improved airflow through the turbocharger and releasing more power potential for your 1.5L engine.

Due to the extremely complex nature of this part, our requirement to retain the OEM BPV, and our goal for a single-piece design the team here utilized cast aluminum construction for the turbo inlet pipe. This provides a lightweight and simple part for you while allowing for the design flexibility to hit our objectives. _{*prototype pipe shown}

All pieces are manufactured from A356-T6 aluminum and post machined to a precision fit for both OEM and W1 style drop-in turbo upgrades.

We pushed the limits with our design and this required that we make changes to both the sealing surface to the compressor and the valve cover breather hose. Good news though, we’ve designed and included all the necessary components for a complete and seamless install.

Mounting studs, gasket, silicone valve cover breather hose, mounting bracket, silicone, and a new wiring harness shrink wrap are all included with the turbo inlet pipe.

Our upgraded turbo inlet pipe pairs excellently with our W1 upgraded turbocharger kit. With optimized tuning we saw gains north of 13whp and 14wtq. This testing was performed on a 2018 Honda Civic SI with standard bolt on modifications on pump gas.

With increased flow and less restriction an upgraded T.I.P can help feed the turbo with fresh air and even give a louder induction noise for those looking to make a statement with this upgrade.
