Add Intake Porting: * 

Want to take your LS3 Intake Manifold to the limit? Porting the Manifold also includes stand removal, and epoxying the manifold floor for maximum airflow!

*We don’t recommend this for forced induction setups, as removing the stands decreases the structural rigidity of the manifold.

(Intake Porting is a very popular and time consuming process. Please allow extra time for shipment if selecting this option. They are fabricated on a per order basis.)

Add Intake Manifold Heat Shield * 

It works by shielding the intake manifold and reducing the heat radiating up from the top motor. This lowers intake manifold temperatures creating a more dense fuel and air mixture, creating more power. Think of it as an intercooler for your intake, same physics and chemistry just a different way to get there.

DO I HAVE A CREDIT LIMIT WITH AFFIRM?


Unlike a credit card, Affirm is not a revolving line of credit. While customers can take out multiple Affirm loans at once, each Affirm loan application is evaluated separately as a closed-end transaction. An application from a returning customer may be denied, however, if that customer has failed to repay other Affirm loans on time or if the customer shows excessive borrowing behavior.

HOW DO I PAY MY BILLS?


You can pay your Affirm bills online at www.affirm.com/pay. They accept payment by debit card, bank transfer and check.

DOES AFFIRM PERFORM A CREDIT CHECK?


Yes, when you first create an Affirm account, Affirm perform a ‘soft’ credit check to help verify your identity and determine your eligibility for financing. This ‘soft’ credit check will not affect your credit score.

WHY WAS I PROMPTED TO PAY A DOWN PAYMENT WITH A DEBIT CARD?


Affirms tries hard to approve every purchase but sometimes can’t approve the full amount. When this happens, Affirm provides a debit card down payment option so that you may still complete your purchase right away.

WHY WAS I PROMPTED FOR A CHECKING ACCOUNT?


Affirm sometimes requires additional information to consider a credit application. Such information may include an active checking account, which helps Affirm verify your identity and your ability to repay the requested loan. If they prompt you for this information but you are unable to provide it, Affirm will be unable to approve your credit application.
