Wanting to get the k&n Sri intake and sell my injen intake. Would this really screw up my fuel trims that bad of needing a retune?

 

Someone else may know better...

But I'm thinking if you went from stock intake to K&N it's not such a big deal.

But if you were custom tuned for the injen and then switch to the K&N. Yep... You'll need a retune.

 

Every intake changes fuel trims differently. Some more than others. Would it hurt going from one to another without changing the tune, probably not. But would it be ideal to tune for the new intake, yes.

 

I plan on retuning with Hp in the future after I get the new clutch in and all that good stuff but that probably would be next summer. But if it would throw my car off pretty bad I'll just pass on getting it for a while .
