CAI/Induction. Alta vs GTT vs JCW/GTT vs K&N etc... Which to choose?

[DaFlake]

It is a nice looking CAI Roland

Roland, thankyou for the explanation.

Puting a little breather on the hose that vents upstream of the throttle body is an automatic $345 fine in CA even if it is re-attached and referee checked. No "fix it-sign off" second chance. I ran mine for three years without problem, but got a traffic stop by a cop who ticketed me for "modified exhaust" and he searched the car including under the hood. The exhaust deal was bogus as it was all from the cat back, but he thought the SuperTrap diffuser was a violation. I got that signed off easily as it was all legal and within sound limits, but it gave him the "right" to search the whole car as that's the law here in CA. When he saw the filter on the hose he was SO happy. I was hoping it would be technically OK for emissions, but according to your explanation it is still needed to vent crankcase fumes at WOT.

Got to agree with Jon (oh it pains me to do this!) and futureal

I have the Alta mysef with the rear panel removed and its sounds immense.

Can't go wrong with either kit TBH, but if it was my money again, I'd still go Alta.

....tbh just leaving the hose connected (stock) is fine, the amount of air coming through it at WOT is small. Even on GTT250-GTT260 conversions etc we leave as is .

Roland,

I'm back from my visit to the California Air Resources Board Referee as was required by my traffic ticket.

Unfortunate fact of life in California: any modification at all, even ones that would reduce emissions or increase gas mileage, are illegal and subject to the $345 fine if they do not have a CARB sticker indicating official approval by the state board. This includes an oil catch can as it is attached to and becomes part of the PCV flow. According to the referee, the intake system is also part of the emissions control equipment and as such is required to have a CARB sticker. This would include any CAI filter arrangement even if attached to the original hose as it is a change from the factory panel arrangement.

This may seem a counterproductive state policy, but it makes sense to the simpletons in the governmant.

[DaFlake]

Cali has always done their own thing when it comes to emissions. Some say they are cutting edge and others say they are big brother. As with any product you have to conform to local policy. Here in Germany my CAI would not pass inspection. However, I don't go to the locals for inspetion but rather a group here on the military installation. Because of this I have a set of slacked rules and I can get it passed.

Most Germans will go to inspection with stock and then change it again after. If they are caught they pay the fine....

Question for Roland:

Sorry to change the subject for a moment, but did I read somewhere that the GTT Oil Catch Can is fitted differently to the Alta one? I know that people with the Alta one have had trouble with water getting into their oil (plus the GTT one looks much nicer). Also, is it easily removed so that the car can is standard again (should I decide to sell the car to someone, and don't want them to know it's ever been played with)?

[Lunding]

Will there be any issues with the Alta Air Intake System 2.0 and a Works Strut Brace ???

[AMF310182]

Good question, I'm probably gonna have a Works Strut Brace too.

Hi ,check our website ,you can see a pic of the GTT OCC .It mounts onto the stud at the earth strap to chassis . GTT Cold Ram Ind kit can be modified (very neatly) to accomodate GTT Aerobox Strutbrace or JCW.
Best Regards Roland GTT

Sorry, I meant the way it is plumbed to the engine, not the way it is mounted in the car.
