Whats goin on guys,
New to the forum, had my 07 g35x sedan for about a year now. I am looking to do alittle mods to it to speed things up alittle. I figured id start with a cold air intake. Any suggestions what brand or what website to shop. the k & n one looks pretty nice, any other suggestions? I was also curious what would my next step be and exhaust? If any one can recommend anything i'd appreciate it.

Try to use the search button. Just for starters the gains are not going to be huge for speed unless your willing to drop a good amount of $. Cold Air is a good start.. slight gains and makes the car sound like it has some get up and go ! All the main brands are fine AEM KN INJEN FUJITA etc.

You can look here for the parts
http://www.g35parts.com/

and try to find them on google or ebay for cheaper is probably your best beat.

For the next step for performance if you don't want to go FI would be:

Plenum Spacer
Grounding Kit
Throttle body Spacer
Cat Back Exhaust
Test pipes if you dont mind the noise
then a good tune and enjoy it unless you really want to spend money and do some serious engine work.

oh no, he said throttle body spacer ^^ Here we go again............

we don't need to go any place again... it is just an option. I don't have one but if he wants options thats one he can do his research. No need to start up some stupid rant if its this or that
