On a hot day and sitting idle with the engine up to full operating temperature, the intake temps go fairly high at around 110 to 120 degrees. As soon as I start moving the temperatures drop dramatically and once I'm driving at more than about 30MPH, the temperatures are within a few degrees of ambient temperature. Any of the silicone based tubes should perform identically unless they have extremely thin sidewalls.

I am very curious to see how hot the temperature gets with the G3 intake since the intake pipes are metal and much longer, which should be terrible for heat soak. I would also expect the temperature drop to occur much slower once you are moving due to the amount of mass that need to be cooled with those tubes. Hopefully someone with the ability to measure intake air temps will get G3's soon so we can compare temperatures. I have a feeling that dyno numbers and real world driving numbers will be dramatically different.
This is good info, thanks. Would you think that a Silicone tube that is thicker would help the temperatures more or waste of money to switch?

I doubt there would be much difference unless is was substantially thicker, but that would make it very difficult to install. Silicone does not conduct heat well, so as soon as air velocity increases, the internal temperatures of the tubes cool quickly regardless of how hot they feel on the outside. I am curious to see how long it takes the long tube intakes with metal piping to recover from heat soak. I expect it to take much longer for the temperatures to drop and they probably will never get as cold as the stock or HPS temperatures due to the long metal pipes. The stock positioning of air draw is ideal for getting cold air in without water ingestion issues.

Today received Z1 hoses. Really fast shipping to Europe (got FedEx at same price as USPS express delivery). Glad to chose Z1 ones, they look really nice. Tomorrow will be installed, so will see if is necessary to unmout strut bar.

Probably not totally necessary, but made it much easier.

I wish there was a way to remove the stock crank case vent hose and add a new, more flexible one instead of the hard plastic that goes into the intake tube. This is what seems to be giving me the most trouble for whatever reason...
i just put the breather on and did not put it back on its holder. it seems sturdy enough to hold its own. plus my tubes are round all the way for better air flow.

my HPS tubes are available. $85 shipped in the CONTUS. Approx 3000 miles on them.

Can't decide on the color lol, blue or black?

I'm leading toward black.

Necro bump.

Alright guys, I just installed my Z1 Post-Maf tubes, but I didn't use any of the clamps. The tubes fit super snug and I didn't think anything of it as they were pictured on Z1's website without any of the clamps installed. Then I look here and everyone has the main clamps as well as the annoying little ones. Should I not worry about it or tear it all apart again to put the clamps on? It'll be a few weeks before I have the time again...

Necro bump, lol. My worry would be that the material will expand from heat...and then you are sucking air in places you don't wanna be....

I'd put the clamps on just to be safe.

You can get the clamps on without taking the tubes off btw. Just unscrew the nut on the clamp all the way until it comes apart

I'm sure it is fine for the time being since the tubes are under vacuum when the engine is runnin

K&N drop ins are the way to go,,,,
What intakes have you had on the car, just curious?

Received mine yesterday. Not expecting any noticeable hp gains, just want to clean up the intake at a reasonable cost. K&N drop in filters helped the throttle response.

Instructions say to remove strut bar, engine cover, and a half dozen other intake items, along with disconnecting the battery and MAF sensors. Thinking this is overkill.

Plan on trying to squeeze this in like everyone else, if necessary I'll remove the strut bar and/or engine cover.

IMO the MAF sensor is not being changed or moved so no reason to disconnect.

OK, so I did the install this morning. My observations.

I did not remove the strut brace. I did loosen the stock airbox to allow some wiggle room, also helped to remove the front part of the engine cover to get to the one bolt on the passenger side for the PCV.

I had to trim the small PCV nipples as they would not allow the tubes to sit properly. Easy to do with an xacto knife. Be patient and expect some lost skin. The tubes are flexible so you can bend them quit a bit.

There is a resonator box on the stock tubes on the driver's side this is not needed after the install. Removing the clamps from the stock would require cutting off the rubber nipple that holds them in place... your choice.

After inspecting the stock tubes vs the HPS. I can't see how this will add any hp, but is more for dress. Will get cleaned up and take her for a spin today.

Debating about disconnecting the battery to supposedly reset the MAF sensors. Anyone else tried this? Results?
