    An intake manifold is an integrated assembly that sits atop the engine, consisting of a series of tubes which distribute fresh outside air to each and every cylinder. On V-shaped engine blocks, an intake manifold typically sits between the two cylinder banks while inline engines may feature a manifold to the side of the cylinder head. Intake manifolds serve as a...
    Most aftermarket air filters are constructed from multiple layers of cotton gauze, which are sandwiched between wire mesh that is formed into pleats. The layers of oiled cotton fibers are able to trap dirt particles that are even smaller than the holes in the filter media. The airflow stays consistent between cleanings, for optimal combustion.
    The easiest way to improve airflow to your engine is just by changing your stock air filter to an aftermarket performance air filter. There’s an aftermarket air intake system for every budget and every application. Even if you have a hot rod or custom car, or if your car’s just not listed in a catalog, you can still get a quality system. Everyone, regardless of...

    2008 Honda Civic Si | Posted by Wendy | (Moncton, NB)

    My OEM filter was pretty bad before I changed to a SRI so I noticed significantly better acceleration and there is a Dramatic change in sound especially in VTec. Product was as described, delivered in good condition. I didn't like the hoops I had to jump through to get past the fraud management at CarID.com, shipping and billing address are the same and Mastercard approved the purchase but Carid.com held up the order for almost a week waiting to confirm that I was the person ordering it? Fraud management isn't to protect the customer, we have that with our credit cards. Its to protect the business against losses and its really really annoying. That being said they were polite about it, and once the product was in the mail, it was delivered fairly quickly to New Brunswick, Canada. The product loses points in installation for me due to the finicky nature of the design in that it has to be positioned just right to make sure the end of the filter doesn't rattle on the brake master cyl. If this happens to you, just check that the filter is slid onto the tube far enough. It is however one of the only intakes that you can put on an SI without the check engine light coming on, so kudos INJEN. Make sure during installation you install all of the clamps in a way that you can loosen and tighten them while the thing is in position on the engine in case you have to adjust after running for a little while.
