As a new ISF owner I am loving the car, but an starting to get the mod bug. But due to budget constraints am only looking at an intake at the moment (eying that JoeZ Exhaust though!) From what I've read in some of the posts on here about intakes it seems that they all rob power from the car due to heat soak. Is there any intakes that are out now that are worthwhile getting?
Thanks in advanced,
CK

Joe-Z or HPS and a drop in air filter (aFe or Tom's, don't go with an Oiled filter)

Rest seem to rob power. The exhaust is a good mod, but the headers gain a lot more power.

Wow! Thanks for the response. Didn't realize how close the Headers were to the Exhausts in price. Well then I'm looking at the PPE headers now haha.

Would adding the Headers in before the an exhaust and intake upgrade be wise though?

I would get intake & header first. PPE header or Sikky added about 30 hp. For intake I like HPS.

Will the HPS Tube change the sound the car produces on a stock system?

When I had my HPS intake, I did notice more air turbulence. It's not too noticable.

Can't say I noticed it on mine?

Then again, I went from the Takeda to the HPS and performance dry panel filter, so big noise difference.

Also found close to 10HP and ironed out an issue with my AFR readings.

Have a read through the build threads when you have some free time. Lots of experiences and good advice in there.

My favourite intake option is the titanium one from LEMS.

Only thing is its $600 or so!

Best of luck with your mods chap.

Cheers.

Thanks man. I'm deciding between an Injen or a HPS with a Toms Filter. I want a bit of an increase in sound. I have read some posts saying the Injen does succumb to heat soak, and other say it doesn't! So I'm quite confused but I'll keep on trucking and try to figure things out. Can't find any videos of a stock ISF with just an intake installed.

I thought i read that Intakes don't really "add" power to these cars and the factory setup was actually engineered very well. Is this not true?

I even saw a dyno graph somewhere where the stock outperformed 2 of the 3 aftermarket intakes installed..

From what I've read, if you want sustainable power get the JoeZ, HPS, or stick with the OEM. I just want to find out the differences in noise between the Injen and Takeda. Found a video of a stock ISF with a Injen but can't find one with a stock ISF with Takeda. I think I'll end up getting the Injen or the HPS with the Toms Filter.

Yeah LEMS can leave you speechless



Lems

I have it set up with a blitz high airflow filter. Left the pockets empty but satisfied with the look and performance.

Now that's a thing of real beauty!

Just need the battery tie down now to complete the set!

One day my precious, one day!
