QUESTIONS & ANSWERS
Ask a Question-
Why must the egr cooler be removed for this to fit? Are there any options for full emissions trucks? Thanks
The larger size of the mouthpiece have issues with clearing the egr cooler. HSP told me that you will probably have some fitment issues with egr in tact
-
What size is the O.D of the tube that doesn't have the v-band?
The side that the intake goes on is 4" OD
-
The description says it will fit emissions or deleted applications. But one of the questions says it may have fitment issues with the egr cooler. Any one know for sure if there's fitment issues? Thanks!
This fits emissions intact

Sir / Ma'am, I am ordering the RPI intake system and selected Illusion Blue as the powder coat color. Is this candy blue a similar shade, or is it darker than illusion blue? Also, I noticed that you said there may be fitment issues with the HSP turbo inlet mouth peice with the factory EGR system still in tact. Does these fitment concerns cause rubbing or just difficulty aligning the turbo inlet clamp? If fitment is an issue and inlet is powder coated is the item still returnable?
Yes the candy blue hsp uses is the illusion blueberry, it does fit with egr still in tact. If for some reason it did not fit yes you could return it.

I see how it connects to the turbo but how does it connect to air intake side
The stock silicone boot that attachs your intake system to your oem mouthpiece is used.
