K&N Typhoon Install problem

VaGntlmn · 09-04-2010, 07:59 PM

Anybody else run into this one?

I was attempting to install a set of K&N short intakes on my car this afternoon ('10 370z Tour/Sport), and everthing was going fine until it was time to connect the new intake tubes to the valve cover vents.
K&N thinks the hoses are one size, when in reality they are another size (i.e the hoses that they gave me are too small to fit on the valve cover vent connectors).
Anybody else run into this or have any suggestions??

And of course, now I have to spend part of tomorrow putting everything back to stock

Update: Saturday, 9/11/10
The key is 3 tries, a little bit of extra knowledge, boiling water, and liquid soap.
Before attaching the 1/2" hose to the 5/8" vent covers, put a little bit of liquid soap on the outside of the vent cover, and soak one end of the hose in boiling water for about a minute. You still have to work fast, but it can be done.

I just forced it in and put clamps on it. I thought I was forgetting something and kept referring to the pictures but it looks like I did the right thing.

2k miles later, everything is still working correctly so I'm fine with it.

Yep I had the same issue. The hoses are too small and I had to force them on. I heated them and used some soap to try and get them on easier. PITA

Well, you guys must be a little bit braver than I am.
I went down to the auto parts store this morning and was able to get a couple of straight 1/2" to 5/8" connectors.
Although they might work, I didn't like the way they went together.
I think I'm going to get a couple of 1/2" to 5/8" 90 degree connectors and then try again.
Thanks for the responses, I really appreciate them.

VaGntlmn · 09-05-2010, 06:23 PM

I was so glad to see the responses and find out that I wasn't crazy that I forgot the major questions.
1) do you like them (and does it make a difference)?, and
2) did you do any thing to get them fresh air (like fang vents, etc)?

tjlazer · 09-07-2010, 11:44 AM

I like them, they are easy to install/maintain and look/sound great. I also did a Dyno and I made 6RWHP across the board. But the after dyno was 20 degrees hotter than baseline, so I am sure the # could be higher. I do feel the power increase as well.

I added this resolution to the bottom of the original post, but wanted to add it here as well.

Thats exactly what I did. I did recall trimming one hose a little as it was too long and had a kink when installed. They need to supply better hoses IMHO.

I installed mine today, and ran into the same exact problem. Everything went fine until I had to connect those last 2 hoses for the ducts. I spent 2 hours trying to push it on, cutting my fingers on everything sharp within the engine. Finally I checked this site and came across this post, thankfully!! After putting hot water into a Pyrex measuring cup, then into the microwave for 2 minutes, I then put that water into a pot on the stove that was on high. This allowed me to get the water to a boil in less than 4 minutes. Once it was at a boil, I added the 2 tubes. I let them boil for 1 minute. During that time, I put Palmolive on my fingers, then on the 2 plastic pieces the hoses need to connect to. When I was done with that, I brought out the pot with the tubes still in it to the car. I used gloves to grab the tubes, and quickly pushed the tubes on. You do have to be quick about it and you also have to be careful where the natural bend in the tube ends up. This is because if you're not careful, you could force the tube to crease, aka fold, and reduce the airflow. I'm really happy with the end product and they look great once installed. Haven't taken the car out yet but I did start the car to hear how it sounds, and I'm very happy with it.

K&N should throw in a free package of Ramen or mac and cheese given all that water you had to boil!

tyler20c · 12-22-2010, 10:42 PM

What exactly are the smaller hoses for? I heard something like a "breather". Also, when installing mine, It was hard to ensure a 100 percent perfect fit so is it a huge deal if one of these ends up coming disconnected at some point?

Sibze · 12-23-2010, 11:49 AM

I ended up using the stock tubes and then used the clamps, worked great

Kastley85891 · 12-23-2010, 12:21 PM

Minor issue but one that should not occur, if a part is sold for a particular vehicle it should fit, if it does not then its just sloppy design, that **** pisses me off no matter how insiginificant.

DonV · 12-26-2010, 09:39 PM

I installed hte system last week and had no problems at all. All you need to do is cut a small 45 degree chamfer on the insidede of the end of the hose that goes on the valve cover with an X-acto knife and hit it with a little WD40. Mine went right on. The only thing I noticed was that the passenger side hose was way too long an after cutting it to a length that kept it from kinking, I did the same mod to the valve cover end and it went right on.

When I first got my Z last month I immediately replaced the factory filters with K&Ns, as I have been doing on my vehicles for the last 20 years or so and kept the stock airboxes. I noticed a mild gain, and then bought the Invidia exhaust, but still nothing exciting. I then decided to take the plunge and get the Typhoon system, which I got for a little over 300 bucks on eBay, and the difference in perofrmance is astounding. I live at close to 6000 feet, so perhaps the extra airflow accounted for the noticeable increase in performance, but having read all of the threads about how only the Stillen tubes will give a real performance gain and that the Typhoon is little, if any better than the stock airbox with K&Ns or other performance filters, that definitely has not been my experience. Definitely worth the investment.

tyler20c · 12-31-2010, 08:35 PM

I have the hoses on but my question is what are the hoses for in the first place?
