I am hearing alot of talk there SRI do not improve performance much (in fact reduce at low RPMs). Will putting in something like KN cone air filter improve performance by a bit?

 

Get Stillen G3 CAI or keep stock...

 

Nothing wrong with the stock intake. There is some power to be made, but frankly I would just get some drop ins.

 

What are drop ins? Can you give me an example.

 

Infiniti G37 Air Filter - Replacement Air Filters

 

Umm will these really make a difference they look just like the stock ones.

 

I think somone should build a scua for air to be rammed into the SRI from the grill or bumper

 

Do drop in really make any difference? Also are HKS-hybrid filter really that good because the cheapest set is like 70 dollars

 

thought hks drop ins are like 55?

 

perhaps IDK i was curious if the HP gains would even be 5hp? also does it really improve throttle response cuz that what I really care about

 

The G37 has a very well designed Air intake system. Although there are some improvements to be made, the stock intake was designed to disperse the airflow over the MAF properly. Although some intakes like the stillen Gen 3 add horsepower I would be concerned about running a little lean without a tune.

I really don't think that you would notice any seat of the pants gains from either the drop in's or the CAI. I am not saying they don't work, but the air intake on the G37 is similar to that on the GTR which is running twin turbos. There are several 600 WHP GTR's running around with a stock intake track.

This is why i say get drop in's they are much less expensive and they increase some airflow since the stock filters can be restrictive. Many top tuners say the biggest bottle neck on this car is the stock cats and to me that's where I would start.

 

Don't even get drop-in filters.
Cobb and many other people have already confirmed that HKS drop in filters alone lean out the fuel curve.

Stock intakes or Stillen G3.

 

more info on the HKS filters causing leaning?

I wouldnt think these filters would alter the readings that much. Still wondering if cobb's post maf hoses are beneficial.

 

Even though they tested on a EVO, I expect similar effects after all.

 

hmmm interesting. Thank you.

i know they are all about a/f and proper air intake so maybe they are right. Maybe they have something with just the post MAF hoses...
