If you want to use a larger throttle body than our 59mm unit, you'll need to port the upper intake to see any more gain, because the stock port size is 58mm.  For those customers who only want an upper intake manifold, we offer this part by itself for a very affordable price.  All of these intakes have the throttle body inlet ported to 65mm to accommodate aftermarket throttle bodies, All 3500 intakes get ported to 68mm.  You can choose to only port the throttle body inlet, or do our full port job.  If you choose full port job, this is the same upper intake we include with our ported upper and lower intakes.

Our full port-job exceeds what one of our competitors calls a "competition port job".

You may have noticed we've updated our pricing.  We recently did an extensive cost analysis over the last two years on all of our ported and polished parts, and have increased the prices accordingly.  These new prices are based on the amount of time it takes to port these products, which we came up with by keeping logs for each and every ported and polished product we've sold during the last two years, of each type that we sell.  The labor portion of these prices come from a rate of $50/hr, which is half of our $100/hr shop-rate.  So it's literally as cheap as we can do it.  Our Stage packages will have discounted pricing when combined with the other parts within those packages.  So as far as this intake's pricing, we went from a $75 difference between throttle body only to full port job, and reduced it to just $55.  The reason the product price jumped so much is due to the significant amount of time spent cleaning/prepping the parts for porting, as well as cleaning after the porting is done.  So whether you get the half port job, or the full one, the cleaning is the same.  Each intake is cleaned thoroughly and then glass-beaded to remove all exterior dirt and debris, and as much as the interior as is accessible with the blaster.  In the 3100, 3400, and 3500 upper intake, there are areas in the plenum where the blaster can not reach.  After porting, the intakes are once again thoroughly cleaned with solvent, then each and every threaded hole is cleaned out, and then the part is once again cleaned with solvent and then blown dry with compressed air.

So I apologize for the increase in cost on this item, but I promise it is necessary to retain the highest possible quality of this product, without having to ship customers dirty or improperly  cleaned parts.  Any customer who sends us parts to be ported (or as a core afterwards) which are pristine and require no pre-cleaning at all, will receive a credit for the cost of the pre-cleaning we would typically need to do.

We will be updating these outdated pictures in the near future.
Please allow 15+ business days for your intakes to ship out once cores and payments have been received.
