Introduction

This document is intended to highlight the complete installation of Vivid Racing's Dual Snorkel Air Intake assembly on the Porsche 911 Turbo. Thanks to doing a special custom fabrication run of these units in a simple Matt Black to go with the rest of the car's stock engine bay components, we asked and we received.

This particular install was done on a Porsche 2005 911 Turbo “S” Cabriolet. The main object of installing this unit is to effectively double the intake air available for the engine to breath better. The system is also said to generate a little more horse power, but no figures for this are available at this time. IMP Concepts ONLY advocates using the OEM type Paper Filter as opposed to those based on Oil of any kind. The OEM MAF is known to fail when using these alternative types of Air Filters. 

This document is intended to be a helpful installation guide. If you follow the photos you should be able to complete the installation safely and have some fun while you are doing it. The separate sections of this installation are intended for reference, they were not necessarily carried out in the order they appear.

You will notice things like the covers and OEM air Filter Assembly have been removed in the photos. We will not go in detail how to remove them, the information can be found in the Porsche 996TT repair manual. 

Objectives

 Before we embarked on this project we set the following objectives: 

Parts Required

  • 1 x Vivid Racing Dual Snorkel Air Intake Kit - Mandatory

  • Foam Door Insulation (Exterior Type) - Mandatory Provided with Kit

  • Aluminium to Re-Fabricate Provided Retaining Bracket - Optional

  • Some Flat Matt Black Touch Up Paint - Optional

  • Electric Sander - Optional

  • Tin Snips - Optional

 

Tools Required

 The Vivid Racing Dual Snorkel Intake Kit

We are very critical and would consider the quality of these parts to be adequate. The general look is good. They are glass fiber, so you will see pit marks in them from the mold, we would have liked to see them filled in but in most cases the flaws were on the bottom and cannot be seen. The paint is OK, but will chip here and there during installation, get some Matt Black touch up paint so you can fix all this after the install. simple Flat Black paint will do the trick. The following are some photos of the kit.

Installing the Second Snorkel

 First you need to remove the fan and associated hardware. Then you need to remove the back plate, it looks and feels like fiberglass. If you have a Turbo "S" you need to be VERY careful with the Wing elevation hardware. We temporarily tied it with tie wraps to the engine cover latch. The hydraulic pipes are plastic and look as if they can easily be stretched or damaged if treated poorly. Also, be careful not to shut the engine bay cover until you are done.

The provided second snorkel fitted quite well we had to increase the size of one of the holes because it was slightly out of alignment. but all in all it was a good fit.

You will have to remove the mounting plate for the fan as it needs to be cut. Be very careful with the Rear Spoiler mechanics. Do NOT stretch the pipes, we tied the hydraulic assembly to the rear lid while we were working so as not to stress the pipes.

Cutting the Hole in the Fan Back Plate

We chose after all NOT to create a template, it was far easier after some thought to mark the Back Plate and then cut it. The back plate is made of fiberglass composite and quite hard. As you can see in the photos we marked the hole we wanted to cut and them applied masking tape so we did not damage any of the stickers. We used a Jig Saw and a Ceramic File Type Blade to cut the hole. first we drilled 1/2" holes in each corner and cut from there. We made an effort to preserve all the stock stickers. Clean it up with a file when you are done.

Preparing the OEM Air Box

You have to remove the flange on the OEM Air Box as the new part has to fit flush. We used a pair of Tin Snips to simply cut off the excess plastic. We then used an Electric Sander to clean it all up.

Installing Second Snorkel

Simply reverse what you did to remove the back plate and install the second snorkel in the holes shown in the photo.

Installing The Upgraded Filter Box

This is fairly straight forward, the cover provided fits quite well onto the OEM Filter Box Back. Simply assemble it as you would the OEM cover. 

Hint: We recommend applying some Blue Thread Locker to the nuts as they have no retainers like on the OEM setup. The LAST thing you want is one of these coming loose in your Engine Bay.

We chose to do 2 things differently, firstly we used the OEM plastic protectors (You will need to cut them to size for each hole in the provided back) when putting the retaining screws in, secondly we were not really happy with the bracket provided with the kit. While it is most likely adequate, we thought it was a little flimsy, considering the unit did not include any lower supporting mounts to mate with the OEM rubber bushings.  We chose to make our own bracket our of a more sturdy 1/8" Aluminum plate. In addition we raised the whole unit up about 1/2" as we did not want it resting on the cars chassis. We have water injection feed pipes under it, along with some wiring, so we made our bracket to take this into consideration and used the OEM rubber support. We would have liked to see some lower supports like the OEM back had, but again that would have been our preference the unit as supplied is probably adequate for the application.

Modified Bracket (Prior to Painting)

     

 

Completed Unit Installed and Aligned (We are going to repaint it all including the bracket as there are a lot of scuffs from installation and manipulation)

We also want to paint the inside so you cannot see the raw fiberglass, it can be seen from outside the car through the grill and when you open the engine bay. We feel the overall paint job could have been a lot better, a good quality 2 pack epoxy paint would have been a better choice for the real stealthy look we are trying to achieve. There are also a lot of pits in the fiberglass, these could have been filled before painting for a more professional finish..

Why We Want to Paint it all Inside and Out

Additional Bottom Support Brackets

Well, after some testing we found that the modified air box sat too low in the engine bay, this is due to the fact that Vivid omitted a crucial supporting bracket on the bottom of the unit. There are 2 supports on the stock air box that mate with 2 rubber dampening grommets when installed. The one of the right is not so important, but the left one proved to be crucial. We noticed the air box sat a little low and was not very stable once installed.

True to form we constructed 2 new supports out of stock aluminum that have completely addressed the issue. There is a template available for those who wish to add them. We just lined them up with the stock air box mounts for measurement purposes.

This makes for a much sturdier installation.
