Modifying your 07 Mazdaspeed 3 can sometimes lead to unexpected challenges. One common issue arises when installing aftermarket intakes, like the JBR Tru-3.5, where the provided mounting solutions might not be ideal or straightforward. This article explores a simple, yet effective, DIY fix using zip-ties, along with considerations for a more refined alternative.
Many Mazdaspeed 3 owners who have installed the JBR Tru-3.5 intake have encountered a similar problem: the intake hanger can scratch the battery box. Instead of relying solely on rigid mounting, a flexible approach can be surprisingly durable. As one owner discovered, zip-ties can offer a workable solution. By suspending the JBR Tru-3.5 from an existing bracket using several zip-ties, a secure and vibration-dampened mount can be achieved.
While not a conventional method, this zip-tie technique allows the intake to move slightly, preventing stress on mounting points and reducing the risk of scratches. Concerns about the intake bouncing upwards or wiggling at the filter end are valid, but real-world experience over 25,000 miles suggests these issues are minimal and haven’t caused noticeable problems in this ’07 Mazdaspeed 3 installation. It’s important to monitor clearance, especially near components like the HID ballast, but this zip-tie method has proven surprisingly resilient.
For those seeking a more conventional approach, an alternative using a plastic joint, such as the McMaster-Carr part https://www.mcmaster.com/#7295K43, could be considered. This would utilize the stock hanger stud, offering a potentially cleaner look. However, plastic joints might require double nutting or nylock nuts to ensure a secure clamp.
Another crucial aspect of DIY car modifications is protecting wiring. In this Mazdaspeed 3 example, an old suede work glove was repurposed to armor the wire harness near the intake junction. By cutting open the glove, wrapping it around the wires, and securing it with tie-wraps, added protection against heat and abrasion is achieved.
It’s also worth noting potential issues like battery box scratches. The original JBR hangar design has been known to cause scratching, a problem mitigated by the flexible zip-tie mounting. Understanding these common pitfalls can save 07 Mazdaspeed 3 owners time and frustration during their intake installation.
In conclusion, modifying your 07 Mazdaspeed 3 doesn’t always require complex solutions. Sometimes, simple DIY approaches like using zip-ties can provide effective and long-lasting fixes for common aftermarket part installation challenges. Whether you opt for zip-ties or explore alternatives like plastic joints, prioritizing practicality and careful observation will ensure a successful and reliable modification.
