1FZE Silicone Intake

[Luke84]

I hadn't seen anyone post on this yet, and I know I'd had the problem myself with my intake tube cracking.

Here's a link to HPS Performance's Silicone Intake Tube for the 1FZE. I just installed mine today and it fit in very nicely. Seemed to need a tiny bit more bend, but mated up well. I got mine off Amazon.

I can't comment on HP or MPG gains (haven't had Scanguage connected), and it didn't really sound much different either.

Looks good from my house! Did you loosen and rotate the top of the air can/filter to try and get a better "bend"?

 

[Luke84]

I did- I might mess with it some more, but to get it flush looking on both sides it had little bit of an indentation. I might be able to twist the Throttle Body side to get it straight. I was in a slight hurry tonight, so it may actually mate up perfect haha

Is it possible that the hose needs to be shortened a bit? Too long of a hose could cause the bend and it looks like it is longer than needed.

Thanks for the link. I just ordered the replacement hose kit with the PHH but never saw this item in my searching. One is on its way to me now.

@Luke84 Btw your heater valve is looking sketchy. I would change it out.

I received my HPS intake hose about 2 weeks ago and installed it this afternoon. I did not have a kink in mine and it fit perfectly. Took all of 5 min to do.
Did you try to loosen and rotate the top of the air filter housing as superjuice recommended?

Hmm, isn't the OEM one like $90?

Funny, I was just getting ready to ask if somebody new of a silicone replacement for the factory intake tube. Mine ripped in half the other day installing the dorkel. If its the same cost as the factory one though, well, I'd have a hard time not just giving my money to Beno or Dan.

...and it lasting ~20 years

Had to do that on my 3fe. Just order a section and cut to fit. Works great. Want to do all coolent system someday as they need it.

It is more that the factory unit - HPS sells it for $135 plus shipping if memory serves me correct. But, in my opinion, the air should flow through it more smoothly that the corrugated factory unit. Plus I should not have to replace it again during my lifetime. And more importantly, it is something different.
Full coolant hose replacement is on my list. Got the hoses, just have to find the time.

New hose installed

The old hose was still working but the bottom of the corrugated portion was cracking and would need replacement sooner or later.

I think it's corrugated, or ribbed, because the motor flexes & the air box is rigid w/the fender. The ribs allow it to extend/contract w/the flexing of the engine. I have no idea how much flex the motor actually does but I'd imagine it can be as much as 1". This is all 100% speculation.

 

[TBDAZ]

$135? Maybe $20 on eBay. And I cut 3 inches off of it. Another reason to love the 3fe

 

[half k cruiser]

@TBDAZ I like this option better. Do you have a link to what you bought ? I have not gone out and measured, is there two different sizes between the air can and the throttle body or is it all linear ?

 

[OffGridOverland]

Be careful with bends. As the engine will suck those pipes closed under full throttle.
Also if you are in a CARB state. You won't pass smog inspection.

My rough measuremnts tell me the TB is about 3'' and the coupler at the MAF is about 3.5''. Can anybody confirm or deny ?

I'd like to get one of these hoses off of you if I could. I have a 97 lx450.

Having done plenty of gas flow analysis I can tell you that the corrugated tube, the OEM one, has virtually no effect on air flow whatsoever. Not at these velocities or volumes. The likelihood of seeing any difference in power or economy is virtually nil.
