The stock LS2 intake manifold is a diamond in the rough. With a little bit of work to it you too can see and feel these results. We usually see an average of a 15 horsepower and torque gain
untuned. We have seen as low as 9 gain, and as high as 22 to the rear wheels!
The dyno graphed is a GTO that we simply just swapped the manifold out right on the dyno without any tuning. In fact the computer wasn't even hooked up to the car!
CORE OPTION: Selecting "None" will require you to send your cores in first. We will call and make arrangements. Usually has a week turn around time.
If you need us to send you out our cores first, please select which cores are needed. After receipt of our core, you will have
ONE WEEK to install it and then another week for ground shipping transit time to get returned. Upon receipt of a good condition, working core, we will refund the core charge in its entirety.
If the core is not in our possession within those two weeks from the time you receive it, you will forfeit half of the core charge. If another week goes by you will forfeit the entire core charge and will own our cores and are free to do with them as you wish.
If you intend to keep the core(s), please let us know ahead of time so we can replenish our stock quickly.
If the core is returned damaged, we will assess the damage and determine what is needed to make it right. If it is unusable you will forfeit the core charge for that part. If this happens and you would like the core back, you will be responsible for shipping.
NOTE: Subject to availability of cores. Cores are currently on a 2-4 week back order. Basically depending when customers send their good cores back and pass our inspection process.
