Q: You do not have diameter/size/length that I need of a product?

We frequently fabricate one-off versions of our parts for home mechanics, and for performance shops. Please email us, sales@performancemrp.com, with the details of what you need for your project and we will reply promptly.

Q: Will deleting the secondary air injection system cause my check engine light to come on?

Yes, deleting your secondary air injection system will cause your check engine light to come on. This can be corrected with tuning. Modifying any part of your emissions system is for off-road use only vehicles, please be aware of your local laws before modifying your vehicle

Q: What is an air straightener, and what are they used for?

Performance MRP honeycomb air straighteners screens, available in 5mm & 6mm cell sizes, are aerospace grade 5052 aluminum honeycomb. Our air straighteners are suitable for high-temp applications, they will hold up to being exposed to fuels as well as methanol injection. Our air straightener screens are used to aid in creating a laminar air flow at the mass air flow sensor. This will improve readings “fuel trim” from the MAF sensor, that ECU is seeing. Fix lean and rich spikes, increase throttle response, and improve idle.

Q: Is tuning required when I install a larger/smaller diameter mass air flow housing?

Tuning is application dependent. Generally speaking, tuning will be required when you increase/decrease the diameter of your mass air flow housing.

Q: I can not find the product that I need, can you help me?

Yes, we frequently work on custom projects for individuals as well as manufacture proprietary parts for performance companies, Performance MRP has a full service machine shop that specializes in prototype & production machining. Please email, sales@performancemrp.com, with a description of what you need, a blueprint or drawing of the part if possible, and any photos that you may have. We will reply promptly.

Q: How do I install an air straightener in my intake or MAF housing?

Your air straightener screen should be installed in the intake track before the mass air flow sensor. Typically air straighteners are installed 2-4 inches from the sensor. The air straightener screen can be installed using glue, epoxy, by brazing, or riveting. Performance MRP installs all of our own air flow straightener screens using rivets.
