Mishimoto intake hose issue

370zBLAST · 06-19-2014, 12:21 AM

Has anyone had a problem with passenger side not sitting flush on the throttle body side?..I installed mine today and not please with the way the passage side came out. The clamp will hold it on place but I'm not happy with it

Sorry about the issues you are having with our hose kit. Sent you a PM regarding this!

The issue I have is one of the tube is longer than other one that I have to cut the tube off to make it shorter to get it fit.

I have an issue with my z1 tubes on the passenger side as well. It seems like the hose is just bent at the wrong angle on the intake pipe side....it seats fine but I think the hose might be slightly kinked...havent had any issues tho

I just fitted my Red silicone tubes. The driver side was perfect. The passenger side need about a 1/2 inch trimmed off the smaller breather tube to fit right. I have a 2014 Nismo so maybe it's unique to this car. No harm though, only took a minute and a sharp single edge razor blade to take care of this. I do suggest alternate style clamps for the breather tubes on both sides. The stock Nissan ones most likely will not fit. A cheap solution at any autoparts store.

Overall my review is: They area simple to fit and work great. Hard to tell if there's an HP gain, but I like the clean look and easy install. I would recommend these to anyone that owns a 370 and wants to clean up their engine bay a bit. I just do not like the accordion looking stock hoses.

Just my $.02 worth.

Thanks for the information/feedback guys!

There is a 90 degree/vertical plastic aligning "pin" on the OEM 1" breather tube that aligns with a notch in the OEM intake tube, which makes for a smooth fit. I snipped off the plastic pin and the breather tube connected and inserted smoothly with the Mishimoto tube. Mishimoto tech support also suggested using a little silicone spray on the inside of the tubes to lubricate them when attaching to the throttle body and airbox intake openings - which did help.

Update: I've had a few days to evaluate the car's performance since installing the tubes along with Cosworth drop-in panel filters (Cosworth High Flow Synthetic Air Filter; For Twin Air Box Applications INFINITI G37). My perception is the idle is quieter and the engine surges more smoothly and progressively to 7K . No noticeable difference in power. I'm very pleased with the improvement with the combination of the Mishimotos and Cosworths.

FYI - here's a great source for hose clamp and t-bolt end caps that cover the exposed ends of the bolts and clamps Hose clamp end guards, tail covers items in Clamp-aid store on eBay!.

Hello!

What is the best way to clean those Silicone Air intake?

A little water and paper that does not leave residue?
