HSRK Install

[GRRRR8]

The factory intake air temp sensor is located in the Mass Air Flow meter. Its location makes it prone to heat soak which causes false readings and a loss of power. By installing this kit, the sensor has a faster response rate and allows the ECM to see the true temp and timing loss is all but eliminated. This is the correct location for Roto-Fab. The sensor should be mounted as close to the filter or in filter neck on most air intake systems. Approx. time .5 hrs. Necessary tools: Cordless Drill and stepper drill bit. A grommet is required for install unless mounting in filter neck. GM Part # 24504388.

I have mine in the factory air box, near where the elbow enters that square box just before the throttle body. I guess that is a silencer of some sort. Used a step drill and a grommet and went in fine and is held tight by itself. Have you (GRRRR8) posted any pictures of the stock air box modifications you made prior to your other CAI? I would like to increase air flow but retain the stock box.

[GRRRR8]

No pics but cut the bottom off the factory box where it goes in fender and do the lower panel mod. With a drop in filter it is a nice gain. Move the HSRK before the mass air for cooler air and best gain.

Any pics of the NEP one from anyone? Would like to know if I need the grommet.

No, you would install it in the filter itself. I think G8 Ray has pics.

That's what I thunk! Cheers M8! :drunk2:

Yep! That was mine.

Just got the Roto installed. Noticed the HSRK is installed on the engine side of the filter. Can it be placed on the front side of the filter and would that not be a little cooler location than the engine side?

[wreckwriter]

I suppose it could, might make a slight difference but installing it would be much more of a PITA. I wouldn't want to run the wires over the air box/hood seal....

Mike at New Era still stands by putting the HSRK into the bottom of the K&N Filter of his CAI, but the VMS HSRK wasn't long enough to do that. But it did make a "tested" difference putting it where I did as opposed to the stock one.

With the RF though its not as easy to install it at that point due to the airbox. You have to either run the wires over the seal or cut through the airbox itself to get the sensor into the box. Won't look as clean and could compromise the seal I think. Of course how good the seal actually is is debatable too I guess, quite possibly running the wires over it wouldn't matter.

[Ghouse1803]

could'nt of you just extended the wire down to the bottom of the filter? or is there something in the way?

Top of filter will be faster moving air, therefore cooler I believe.

[GRRRR8]

It should be as close to filter neck as possible. Both pics show best location. I had it in the lower triangle too. 1 degree difference.

[G8GTlawride]

I just finished the HSRK install. Put it in the same place as GRRRR8, only on almost diametrically opposite side. Maybe 120* rotated to the front. Just routed the wiring underneath the inlet and tie wrapped them to the washer fluid neck. I also used the GM grommet that has been talked about. But, the side that is outboard of the CAI tube had to be shaved some as it was much too thick. I think I took an 1/8" off. The groove for the air filter flange was exactly the right width. It sits inside the tube tightly. These are stout grommets. The only problem is I had to buy 5 as they only come in packages of 5 (at least at my dealer).

[GRRRR8]

The dealer screwed up! He is supposed to open the pack and sell you 1.

They were special order. I guess the rules change when that happens. Doesn't matter, they work good, when you thin out the outer flange to allow the sensor to extend deep into the air flow.

Tomorrow is the lower panel cut out.

Do yourself a favor, use a dremel or something. I still can't imagine how George did that with a knife....

Brand new blade.

I must have gotten the "thin" plastic.

Rare factory "light weight" :cool:

So with the HSRK, I assume this really only has effects in warmer temps/lots of passes down a track? Under normal driving conditions: IE: cooler weather on the highway, it doesn't really help much, no?

[GRRRR8]

By the sensor reacting at a much faster rate, the ecm does not pull timing as much. Tuesday it will be 59 degrees and I will bet that I can pull low 50s on IATs at 100mph and I know it wont do that with an insolated MAF.

[JMorris]

I used a grape/linoleum knife. Couple stokes to score it then cuts through like butter if sharpened properly. I use those knifes every day though so they are like an extension of my hand.

Hmmmm.... I believe we have another plastic cutting bad ass among us.

Awsome tutorial. Definitely gonna use this but one quick question. Were exactly is the MAF and how do you connect this to it?

[GRRRR8]

That piece with the arrow is the MAF. You unplug the MAF, then plug the harness in between it.

[G8Smitty]

I got my HSRK yesterday and had it on in about ten minutes. Ray sold me his NEP CAI and had it all setup. No problems.

Thanks again Ray!

BTW - Vector did ship the grommet although I did not need it.

[GRRRR8]

That white HOT is getting hotter!

[-Ray-]

Cool Chris.
The HSRK with the NEP intake is a great combo!

[TouchOfGray]

I am looking into the CAI mod and saw the deals on the OPG kit. I assume the HSRK would install at the filter collar? Couldnt tell from the posts. Any input on cable lenght or other issues? From the photos I saw looks like the filter would be pretty far away from the factory location.

[-Ray-]

The cable is long enough. Some have it in the filter, but the collar is the popular place for location.

[Dan's G8]

Sorry to bring this post up from the dead but if I mount the HSRK sensor as shown by Charlie, do I need a grommet or not?

[JAM]

That is where I placed mine, and I needed the grommet to insure that it remained in place.

VMS provides a grommet. Does anyone know if it will work for the G8/Rotofab application?

:hmm: did you see the pics above? That is a RotoFab. And yes it will work unless you mess it up...

[desertg8]

I put mine under the rubber strip and then unscrewed the rotofab filter. Then I just slipped her in and retightened the filter. no drilling what so ever. I used the inexpensive casper one. It worked better than the rest I had. Not mentioning names.

[mi04se1]

Pics please

WHOA nobody saw this post?! Id be afraid of sucking it in, no?

[travis gore]

I would not see how that could happen. The clamp on the filter would hold it. My only concern would be stress on the wire causing a short. Since this is an old thread it must be working out

[Suckerpunchu]

Mine was installed by shop after the MAF sensor. :grr: Any idea how much of a difference in temp this will make? A post above seemed to indicate 1 degree. Thoughts?

[-Ray-]

Thoughts? The shop you went to has an idiot working there. HSRK install has been posted more times with different intakes than anything else on the board. My mom could install it.
...and bumping a 3 year old post?

[768MPH]

Installed mine last weekend.
Went for a test drive. 61* outside

Temp at idle 71*, normal driving went to 67- 69*.
Floored it from a stop to 60, temp dropped to 62* before I let off the gas. Id say it works and am very happy.

I have to agree with Ray on this one. Installing it after the MAF sensor is counter productive. The whole purpose of the HSRK to get the sensor as close as possible to the coolest inlet charge of air.
