in the plumbing dept at ''homie depot''...rubber flex connector/adaptor for 4''x3'' sewer pipe...abt $10 with clamps...may also need a 3''x3'' flex connector w/ clamps from same source for extension...abt $5.., and a short piece of thin-wall 3'' pipe to join the flex connectors together(a 16 oz can of campbells soup will work--cut the ends out first, eat the soup if you like salt)
fits both easily, clamps draw down a tad for perfect seal and very slight taper into t-body for a ''venturi stack'' configuration (actually might even add a couple ponies)...don't tell spectators where it came from/cost.
Here's another option......Not as cheap as the sewer pipe rubber tubing, but a MUCH nicer fit and finish for sure..........I've tried both the sewer pipe ones from home depot and the hardware stores on several year Vette's and Camaros , and they usually aren't the exact lengths as the factory couplers and sometimes they really have to be streched to fit and they're usually still far from perfect(Just my opinion )...Many guys also boil them for a couple hours in a pot of water to make them more pliable, and In some situations they may be alright, but I prefer these...http://www.mamotorworks.com/corvette?frame=1.689 .........Joe:thumbsup:
''ram intake connector'' (aka 4''x3'' sewer pipe connector) installed between t-body and maF...oem plastic bellows behind...''ram'' inlet is 3'' pipe size, extend to length of oem connector using 3''x3'' pipe connector and thin-wall pipe (campbell soup race product)...can alternately install the 3x3 connector between the air filter housing and the maF if you cut some of the flared end off the filter housing (don't cut the entire flare off)
btw, this genuinely should increase airflow due to ''static regain'' in the enlarged section of the 4x3 connector (was an engineer long ago)
