Have a 98 gs400, and thinking about getting the hi flow intake with ecu and nitrous

 

Dam thats a nice Carbon Fiber Cover where can i find one like this?

 

Srt cold air intake with ecu pigtail. It howls with my protunning.Com catback exhaust.

 

looks clean boss. nice mod

 

Is there much in it in regards to noise and performance between the SRT, Injen, K&N and Weapon-R intakes?

 

Thank you.

 

Who/Where did you end up purchasing your intake through? I was interested in swapping my RMM out to an SRT but was put off by the horror stories I've been hearing about them lately.

 

Weapon R "Secret Weapon"

 

Very cool indeed. Definitely a nice alternative to the SRT. Do you remember the part number(s) from K&N concerning the heat shield and mounting hardware, if any?

 

I ordered from srt. I was told by everyone I got lucky to receive the intake and in only 3 weeks.

 

Got my new 99 GS400 a month ago with 92k miles on it and have been giving it some maintenance love here and there.... But this was the first mod the car needed. Usually, I'd just buy a K&n intake system kit for $300+ and call it a day. This time, I did not want to spend so much money so I started looking for other options. You guys have come up with some sweet ideas. I used 3inch internal diameter PVC pipe painted black with textured spray on bed liner. Also bought the two black silicone couplers on Amazon. I picked up the screw on barbs for the 3 air box hoses at Home Depot (I recommend going to AutoZone instead because I only found 2 in bronze and the 3rd in silver) at the same time I bought the PVC pipe. Also purchased red hoses on Amazon along with a k&n drop in filter for the stock air box. I cut out a large corner closest to the front right headlight to aid in the air flow into the intake. I cut part of the 3/8 inch red hose and split it down the middle to line the edges of the air box cut out, so it wouldn't look so rough along those edges. I drilled small holes at the top and bottom of the cuts to loop red zip ties to hold the edges on tight. Hope this helps ! Lmk if you have any questions

DONE!


Stock vs new, as you can see the pipe is wider so it may require some adjusting during install.
