I'm ordering mine right now...hope there are some left!

 

Thank you. Your package went out today. Let me know when you get it and what you think.

 

It might be a couple weeks before I start on this. I'm actually not even used to the car yet. I havent driven it in almost a week because it's been snowing here and I am only driving my old 4th gen in the salt and snow. The 03 ain't touchin that nasty stuff...Also I've had the clutch replaced upon buying the 03(Oct) and after about 700 miles I am just starting to get on it a little.

 

Wow, fast shipping! I recieved them today.

 

Thanks.

 

Sorry if I haven't read all the pages and its been asked..but. How has everyones experience been with installing these things? Do shops know how to install these properly? How much are they typically charging to do it.

 

Call around to see what a spark plug change runs (since you have 5.5 gen that requires intake manifold removal to change the rear plugs) and you can probably get a shop to install the spacers for a bit more. Try to find a shop that specializes in performance, they should be familiar already with phenolic spacers.

 

Most performance minded shops will install these spacers without any problems. A normal shop should do this for you also. The estimated labor is 2-3 hours. Do not let a shop charge you for more than 3 hours. I can do the job in less than 2 and I consider myself a very slow mechanic.

The Intake Spacers come with full detailed instructions with pictures. Tell them to read over it.

The most common price I hear for a shop to install these spacers is around $150 labor.

 

how does the gas mileage change

 

Should actually improve somewhat, at least in theory to the slightly lengthening of the intake runners (due to spacer thickness) increasing air velocity. Probably why the dyno curve shows a nice midrange torque bump. More torque in the midrange means less throttle to maintain the same speed.

 

Gas mileage is something we have not tested. In theory, it definitely helps gas mileage as Scott mentioned. But since this has not been tested, I can't say what kind of gas mileage gain you will see.

That nice bump you see in the midrange is the VIAS release point. The gain in power when the variable intake releases is very noticeable.

 

I'm about to do this, but I was checking out the dyno sheet and noticed a big increase in power also at 2400/2500 RPMs, am I seeing that correctly?

there is an increase down low but you wont really feel it there since even with the increase, its low HP (~100). you feel it from 4,000 - 5,000 when the IM valve opens.
the increase is in the perfect place in the power band.

Ok thanks... It's really been hard to find non slippery roads around here lately to test the power and get used to it before the install. Most of the time when I floor it, my wheels would just spin as if I had a jack under the front.

 

Whats the perpose of this video? This is just a shot of a car running at 4k and hitting the gas untill redline That vid has nothing to do with this topic. If you watched this video with no sound you wouldn't be able to tell the difference from a stock 6 speed.

 

I will be getting a set asap! Many people on here have purchased these and I have yet to here a bad review on them.

 

you really wanna argue with me about these
i never said the video "showed the improvement that the spacers give".
does the video totally discount everything else i said based on being the first person to have these
please find someone else to try and argue with.
thanks
and nice sig...use someone else's pathetic quote cause you arent smart enough to think up something yourself

 

I’ve had mine forever, coming up on about 9 or 10 months, I need to get them on/installed.


Oh yeah, purpose > perpose.

 

Not much of an argument. I was just wondering what the video ment?

Read post 656 before you say I'm arguing with anything. I know these are good but I don't understand what that video was about? Was it a comparison with something? All I can see from the video was a max flooring it at 4k rpm that sounded like it had a intake. I wasn't impressed! With a camera I can post the same vid if I wanted and I don't have the spacers.

And, Deal with my sig! I may of not made the quote but I do know when to recognize a good quote...

 

My bad, I guess I was sleepen during engrish clss nd typd 2 fst

 

the sound is different with the spacers...the car pulls harder in that RPM range.
i can also recognize a good smart quote....that quote isnt even clever or funny.

 

My car = the quietest w/ the most whp (A33B)

 

mine will be there soon

 

Sound ranges with any intake also. Your vid says nothing for the product. The only thing that does is dyno results.

I never argued the quality or gains of the product!

 

My car = most oil burned per mile. mobpm...And annoyingly loud

 

Have you seen /heard my sound clips. (re: exhaust and intake)?

 

me?
yeah, the post you linked in the DC forum.
thats what im going for. im gonna keep the intake though. just add headers and MAF housing.
just bought an entire IM that im sending Aaron to port and polish.

 

Yes, the 'non' ricer, I like the direction you're headed, Puppet can aid in this 'direction'.

 

im gonna be closer to you when i move back to the states. i have driven joel's car and really like the sound/performance.

 

Yeah, you're reading it correctly. But the gain from 2400-2600 happens quickly and will be tough to notice. But, if you were cruising on the highway and needed that extra torque at that rpm, then yes, you'll notice it easily.

But just like soonerfan said, the biggest gain is right when the VIAS opens!

 

Done!

Finished it up and did the throttle/accel relearn and it drove fine. I didn't do the idle relearn yet...It seems a bit low but that's where it was before. I'll do this later. I can feel the nice little boost at 4K. I could only do this in 3rd gear...2nd would loose traction right there(cold roads), it's 5 degrees here.

I drove around town and racked up 30 miles, 75% hwy. I probobly floored it close to 10 times getting on different on-ramps. When I returned my mileage was reading 26.5 on the computer, so....it's probobly 23 give or take. Happy about that considering the extreme cold temps and wind.

Will it run even better after the computer adjusts to all the new stuff...sparks,air filter, spacers, battery being unpluged for 48 hours?

 

I also feel a nice increase after 4,000rpm. But just driving around town the whistling noise is entertaining too!

 

Reminds me of how entertaining it was to turn off my old Accord and hear the AEM cold air intake hiss. Sounded like a big snake or something!

 

i also like the nice change in the exhaust note

 

That's great! I'm glad you are happy! You'll absolutely LOVE these spacers when the weather warms up! No more sluggish car when racing in extreme temps!

The computer should adjust pretty fast. But I have heard stories about it taking 50 miles or so for it to fully adjust. But in my experience, the ECU learns rather quickly (just a few miles).

 

If you had a before clip to compare that would be great!


I can't wait until it warms up and I can feel the boost in 2nd gear without loss of traction...Kind of reminds me of the 3rd gen I had long ago. I would feel a boost around 5K I think....

I kind of freaked out at the end when I still had 3 important looking bolts still laying on the fender....My pulse started beating a little harder and then I realized those were replaced with yours!

 

It's not too bad of a job for a first timer, huh? As long as you fully understand the instructions ahead of time, then you should be fine.

 

Not too bad...I was really slow at it..It took me about 6 hours I think over three days. I was little worried about getting at the coolant hoses for the tb down there, but once I got them off it was easier than I thought to put them on the bypass you provided, however I wasn't too impressed with the clamping force of the stock hose clamps, I hope they don't end up leaking. I did end up waiting till I got everything apart before fully removing the support bracket near the firewall.

 

It's ok to take your take especially when doing something for the first time. I consider myself a very slow and meticulous mechanic and the first time I installed these spacers on the VQ35, it took me 3 hours and that included noting all the steps for the instructions and taking pictures.

If you find that the stock hose clamps aren't strong enough, it shouldn't be too hard to replace the clamps afterwards now that the coolant is bypassed. But I decided to use barb fittings with 4 barbs per end in order to overengineering things a bit. The stock fitting only has one barb.
